attribute/resource method in locale kit catalogs
* Only load the embedded catalog if nothing else was found, so it can easily
be overridden
* Change the resource type to 'CADA' (CAtalog DAta) for embedded catalogs, and
use a hash of the language code as the resource ID. This allows multiple
languages to be stored in the same file and does not interfere with the user
storing his own BMessages as resources.
