Subject: Restructure things so that the application is now just another
 module. Kohana makes this type of transition fairly straightforward in that
 all controllers/helpers/etc are still located in the cascading filesystem
 without any extra effort, except that I've temporarily added a hack to force
 modules/gallery into the module path.

Rename what's left of "core" to be "application" so that it conforms
more closely to the Kohana standard (basically, just
application/config/config.php which is the minimal thing that you need
in the application directory)

There's still considerable work left to be done here.
