Update centos-art.sh script:
    
     - Scripts/Functions/Commons/cli_getPathComponent.sh: Update release regular
       expression pattern. Instead of using the bracket notation to infer
       optionality (e.g., `{0,1}'), use the interrogation mark (`?'). This
       solves the sed's complains in locale_isLocalizable function.
    
     - Scripts/Functions/Commons/cli_printMessage.sh: Add `--as-suggestion-line'.
       This is another kind of error, but infer a more specific solution
       to the problem. For example, when you are rendering a directory
       structure that don't support localization, the script looks for
       different and equal components of the path in the location you
       provided and compares it with those accepted to receive
       localization and builds a possible match using both the correct
       path and filter option you need to provide in order to achieve the
       rendition action.
    
     - Scripts/Functions/Locale/locale.sh: Remove locale_isLocalizable
       verification from this file and add a comment describing why.
    
     - Scripts/Functions/Locale/locale_editMessages.sh: Add locale_isLocalizable
       verifications here.
    
     - Scripts/Functions/Locale/locale_isLocalizable.sh: Update regular expression
       patterns used to define which locations are and are not localizable
       inside the repository. Remove the $ meta-character from the
       patterns and set it in the verification later. Add support to
       cli_printMessage `--as-suggestion-line' option extending the
       verification of whether a directory accepts or not localization
       inside the repository.
    
     - Scripts/Functions/Locale/locale_updateMessageXmlDocbook.sh: Fix regular
       expression pattern used to find out the main docbook file inside a
       documentation manual. Specify the language information when the POT
       file is created through xml2po program.
    
     - Scripts/Functions/Locale/locale_updateMessages.sh: Add locale_isLocalizable
       verification here.
    
     - Scripts/Functions/Render/Docbook/docbook_doTranslation.sh: Fix regular
       expression used to define path to DocBook locales using models as
       reference.
    
     - Scripts/Functions/Render/Docbook/docbook_expandSystemEntities.sh: Fix path
       to Docbook Default models.
    
     - Scripts/Functions/Render/render_doBaseActions.sh: Verify whether or not the
       source location of the path provided as argument to centos-art.sh
       script accepts or not localization messages. Don't produce
       localized content for repository components that don't accept it.
       We moved this verification here in order to use the value of
       TEMPLATE variable which hasn't suffered any transformation so far.
    
       Fix regular expression used as pattern to build the list of files
       to process. This fix makes possible to use the --filter option in
       combination with the path argument, so paths that cannot be
       localized because of organizational restrictions could be rendered.
    
       Move render_getDirOutput after TEMPLATE=${FILE} assignment.
    
     - Scripts/Functions/Render/render_getDirOutput.sh: Remove locale_isLocalized
       verification from this file. It was already done before at
       render_doBaseActions.
    
     - Locales/Documentation/Models/Docbook/Tcar-ug/es_ES/: Update
       translation messages.
