$template->set_custom_template broken when original template stored in DB

Took me a while to figure out the cause for this one, but some people noted that our tools like UMIL and the Admin Tool Kit which use $template->set_custom_template were loading their board styles template file instead of the correct one.

The reason this happens is when the templates from their selected style are stored in the Database instead of using the Filesystem.

Another case for just dumping the internal style editors which store information in the database?
