Update render module of centos-art.sh script.
    
    - Previously, svg_checkModelAbsref was set to work with file names in
      the form WIDTHxHEIGHT-final.png, where WIDTH is the image width and
      HEIGHT the image height both in pixels. The -final string was used
      to mark the image as final work. This update changes the
      svg_checkModelAbsref to remove the string "-final" from regular
      expression patterns set inside svg_checkModelAbsref.
    
    - Previously, inside svg_checkModelAbsref, both svg_getColors and
      svg_checkColorFormats functions were called without being previously
      defined. This made the centos-art.sh script to fail when background
      images weren't found and it tried to create a generic background
      image automatically, using the color defined by svg_getColors. This
      update changessvg_checkModelAbsref to remove svg_getColors and
      svg_checkColorFormats functions and set #204C8D as default
      background color.
    
    - Previously, svg_checkModelAbsref didn't print any information about
      image cropping. This update changes svg_checkModelAbsref to print
      the width and height of target image being cropped.
    
    - Previously, svg_setBaseRendition was creating temporal files through
      variable concatenation. Such variable concatenation is already set
      in tcar_setTemporalFile function. This update changes
      svg_setBaseRendition to use tcar_setTemporalFile function instead of
      variable concatenation, when it needs to create temporal files.
    
    - Previously, svg_setBaseRendition only verified the mime type of
      design models. When the file didn't exist, centos-art.sh script
      print an error message telling that the file its a text/xml file but
      it doens't mention that the file doesn't exist at all. This update
      changes svg_setBaseRendition to verify existence of regular files
      first and then mime type verification. This way, when the file
      doesn't exit, centos-art.sh script will tell so before printing the
      error message related to mime type.
    
    - Previously, render_setLocalizedXml was using an if construction to
      determine the type of the file and, based on it, define the command
      use to read the file. This update changes the render_setLocalizedXml
      file to remove such if construction and a function named
      tcar_printFile, instead. The tcar_printFile function prints the
      content of the file passed in the first argument to standard output,
      based on file's mime type (e.g., whether it is plain text file or a
      compressed file).
    
    - Previously, to produce artwork for installation media it was
      required to create one design model for each image you need to
      produce. In an environment where it is required to produce artwork
      for different media (e.g., CD, DVD), different releases, different
      architectures, creating one design model per image is too
      inefficient. This update changes the way artworks for installation
      media are produced through a child module name "media". This module
      uses configuration files as source to produce artwork. Inside the
      configuration file you can set the way you want to produce labels
      and sleeves for both installation and live media for different
      releases, architectures with a minimal of design models.
    
    - Previously, file names and file extensions were extracted from paths
      using a combination of basename and sed commands. These operations
      are very common inside centos-art.sh script. This update adds
      tcar_getFileName and tcar_getFileExtension functions to retrieve the
      file name and the file extension from a path, respectively. These
      function standardize the way we do such actions inside centos-art.sh
      script so, as convention, don't repeat the basename and sed commands
      to retrieve filename and file extensions inside centos-art.sh
      script, use tcar_getFileName and tcar_getFileExtension functions
      instead.
    
    - Previously, prepare module wasn't able to create configuration files
      for both render and locale module. This update changes the
      prepare_getOptions to adds the --conf option. This option calls a
      sub-module of prepare named "conf" which creates configuration files
      automatically based on configuration templates and the source files
      found in the directory where the configuration file will be stored
      in.
    
    - Previously, tcar_setModuleEnvironment read module translations and
      module documentation from Locales and Manuals directories in a
      per-module basis, no matter what the level of the module could be.
      Too many levels of Locales and Manuals directories aren't
      appropriate when we package automation scripts. It is not convenient
      to package child modules independently from parent modules because
      the invocation of child modules depends of options defined in their
      parent modules.  Parent modules and all its child-modules are
      considered "an integral module" on its own and it is that integral
      module what we would create an RPM package for. If we package child
      modules apart from their parent module, child modules will need to
      be installed anyway as a requisite for the parent module to work as
      expected. This way, all the documentation files related to child
      modules must be moved from the child module directory to the parent
      module directory in order to be read from there. This update changes
      tcar_setModuleEnvironment to read module translations and module
      documentation from Locales and Manuals directories in the directory
      structure of the first module loaded.
    
    - Previously, svg_setBaseRendition was localizing the source file
      provided to it without verifying whether it was already localized or
      not. This made possible for svg_baseRendition to execute
      render_setLocalizedXml function more than one in situations where
      the source file has been processed before reaching the
      svg_baseRendition function and then call svg_baseRendition to
      complete the rendition process (e.g., see media module).  This
      update changes the svg_baseRendition to localize only files that
      come from a source different to /tmp directory.
    
    - Previously, when there was not a translation file associated to a
      source file, the final file was stored inside the locale-specific
      directory of final the location, based current locale information
      set in the environment. This update changes the file processing to
      store final files without translation outside the language-specific
      directory but still inside the directory dedicated to final files.
      In order to prevent source files without translation from being
      rendered more than once for different locales, you can use the
      --filter option from render module.
    
    - Previously, .po files had a top comment holding the copyright
      information. This top comment make the file (4.17-28) command to
      identify the .po file as text/plain instead of text/x-po. This
      update removes top comment from .po files in order for centos-art.sh
      script to pass verification of text/x-po files correctly.
    
    Update design models used by theme motifs.
    
    - Previously, design models related to installation media didn't show
      the distribution release version very clear. This update reorganizes
      components inside media related design models to show the
      distribution release version in a prominent place. The directory
      structure of localization files related to installation media was
      also update to match the current implementation of locale module.
    
    - Update configuration files inside theme models directory structure
      to match current implementation of locale module.
    
    - Previously, the render module was using the Images directory to
      store final files. The current implementation of render module is
      using the Final directory instead. This update changes the path
      information inside design models to match the current implementation
      of render module.
