Add celeryqueue app

This app will handle all of the async stuff (duh.), particularly the
facebook stuff right now.

In the short term, this is basically just going to sync friends lists
once a day or so using the graph api
Set up signal for djfb
Pull username from facebook
Derp in the proper tags so that this works with Foundation.css
Err out if the user doesn't have geolocation enabled
Move signal handler in to an actual models file
Remove csrf because meh FIXME
Let's actually run the djfb jobs ...
Fill in update_friends tasks and tie them in to the Hugger object
Fix m2m relationship to actually work
Add celerybeat config
Clean up Profile edit controller code by not abstracting so much

Dederp all the derp
Pass friend list in to the view
Show friends' hugs
Only show the chat if you're one of the connected users
Stupid JS back behavior is broken when you post form
Remove fatfingered get() iteration
de-derp the search for friend_objects
Only update friends when the user is first created

celerybeat will take care of them the rest of the time.
Only hide send-message-form when you're not a hugger or huggee

The messages are thusly still visible.
