Support locale-specific resource lookup in QML

In QML there is a need to enable locale-specific resource lookup. E.g. an icon with a house (depicting home) would work well in western locales, but for asian locales you might want to replace that icon with the appropriate chinese character for "Home". Similarly, a Button.qml in Hebrew might use a different layout of the label where the text is right-aligned and the icon is placed to the right.

Such resources could be provided per application / module by using a directory structure similar to W3C widgets "Content Localization";

APP_DIRECTORY/locales/
   en_gb
      icon_home.png
   ch
      icon_home.png

where the application replaces default resources using resources for the current locale.
