Moved all location related queries into CMS_API, instead of CMS_SETUP.

Note that CMS_SETUP provides locations set by default or from configuration file.
Now theme related resources can be found under site/modules/$mod_name/... or site/themes/$theme/modules/...
  so only theme related resources can be overriden for now.
