 CHANGELOG:

 	1. Completely re-wrote the 'edit' portion
-	2. Session variables were disappearing randomly (no idea why). As a workaround, I made my own mini session handling using ActiveRecord. 
-		Session variables would disappear and reappear between requests about 10% of the time, so I added a SessionWorkaround model that holds the action state, as well as the session_id. The session_id doesn't appear to change at all. I tried using an ActiveRecord Session Store, but this caused issues with the Uploadify Middleware workaround.
