[Radiant] import_export patches for user errors (and extensions)

[Sean Cribbs]

IIRC, I left open a hook to add your own models.  I didn't put this hook 
in page_attachments because I couldn't be sure anyone was going to use 
import_export.  Also consider that import_export is half-baked, too.  
I'm of a mind to rewrite it as Rake tasks with dependencies.
