updated the PageRenderer to pass the locale as an argument
updated the GspResourceMapper to:
- accept any file with an 'embedded' gsp extension (like *.gsp.js or *.gsp.css)
- render the resource immediately (this allow us to bundle the generated resources)
- extract the locale to use in the rendering from the resource's bundle name
- put in the generated filename the used locale
added a resource script that duplicates the modules declaration for each supported locale
added a custom version of the <r:require> tag capable to resolve the localizated resource module to include
