Repository's weekly update.
    
     - Documentation/Models/Texinfo/Tcar-fs: Remove License directory.
       Licenses related to Texinfo documentation manuals are reused from
       Documentation/Models/Texinfo/Default/Licenses directory.
    
     - Documentation/Models/Docbook/Tcar-ug/: Rename option from
       `--sync-changes' to `--synchronize' in all docbook files. This is
       for consistency with the same change applied to script files.
    
     - Scripts/Bash/Functions/Help/help.sh: Set `texinfo' as default
       documentation format.
    
     - Scripts/Bash/Functions/Commons/cli_checkFiles.sh: Update
       conditional construction used to verify whether files are under
       version control or not. Don't create another level for error
       messages here.  Instead, use error messages from base (e.g.,
       subversion_isVersioned) functionality.
    
       It is important to note here that when version control is disabled
       in the `centos-art.conf' file, all version control verifications
       are passed successfully, even when requested locations aren't under
       version control.
    
     - Scripts/Bash/Functions/Help/help_getEntries.sh: Update regular
       expression used to retrieve the documentation entry from the
       centos-art.sh command-line with the intention of supporting both
       Subversion and Git directories layout. In Subversion the first
       directory level is for trunk, branches and tags. In Git, there is
       not a need for such special layout in the repository directory
       structure.
    
     - Scripts/Bash/Functions/Help/help_getEntries.sh: Use cli_getRepoName
       function to define the value of manual's self directory name. This
       way we reduce the amount of places we need to change, in case the
       documentation manual used to explain the repository directory
       structure changes.
    
     - Scripts/Bash/Functions/Render/render_doThemeActions.sh: Replace
       regular expression quotes from "...$" to '...$' in order to prevent
       security issues as suggested by gettext application.
    
     - Scripts/Bash/Functions/Render/Docbook/docbook_expandSystemEntities.sh:
       Replace regular expression quotes from "...$" to '...$' in order to
       prevent security issues as suggested by gettext application.
    
     - Locales/Scripts/Bash/: Update `es_ES' translation messages.
    
     - Scripts/Bash/Functions/: Update `--help' option in _getOptions
       files in order for documentation entries to be loaded correctly.
       This change fixes the problem referred as "The documentation entry
       provided isn't supported.".
    
     - Scripts/Bash/Functions/Commons/cli.sh: Don't use eval to execute
       the function. We aren't doing any conditional evaluation here as to
       need a return value. Go straight ahead creating a child
       sub-environment for the new function.
    
     - Scripts/Bash/Functions/: Rename environment variable massively from
       FLAG_SYNC_CHANGES to FLAG_SYNCHRONIZE. Thus, all `--sync-changes'
       options were also renamed to `--synchronize' as well.
    
     - Scripts/Bash/Functions/Vcs/: Don't include getOptions on
       sub-functionalities. Instead, use the same options layer for both
       Subversion and Git and write the respective sub-functionalities to
       perform the same actions based on their specificities.
    
     - Scripts/Bash/Functions/Vcs/: Add Vcs functionality and rename
       functionality from Functions/Svn to Functions/Vcs/Subversion in
       order to use such name as value on package verification.
    
     - Scripts/Bash/Functions/Vcs/vcs.sh: Use vcs_getOptions function as
       interface to Subversion and Git sub-functionalities.  Which version
       control system is used will depend on the value of package variable
       inside the `centos-art.conf' file.
    
     - Scripts/Bash/Functions/: Rename all invocations related to version
       control functionality from `svn' to `vcs'.
    
     - Start using two digits instead of three on CLI_VERSION variable.
    
     - Start using `centos-art.conf' file. This file contains the
       centos-art.sh script configuration booleans. Here you can determine
       whether to enable version control tasks or not inside the
       repository, when using centos-art.sh script.
    
     - Scripts/Bash/Functions/Vcs/vcs.sh: Use the `centos-art.conf' file
       as source to determine whether version control actions should be
       executed or not. For this it was used the "enabled" variable inside
       a "version_control" section.
    
     - Documentation/Models/Docbook/Tcar-ug/Scripts/Bash.docbook: Update
       reference title.
    
     - Documentation/Models/Docbook/Tcar-ug/Repository/History/2013.docbook:
       Add file to start documenting repository changes committed in 2013.
    
     - Locales/Scripts/Bash/es_ES/Functions/Vcs/: Add es_ES translation
       files to Vcs functionality.
    
     - Documentation/Models/Docbook/Tcar-ug/Scripts/Bash/vcs.docbook: Add
       file to documetn Vcs functionality.
