Smoother user experience and bug fixes

- Added intent to post the token to the server, that way the only thing
that interrupts the user's app is a quick spinning wheel from Facebook
- Updated images for submission
- Moved Reauth token posting to PostTokenIntent
- When you press cancel on the twitter OAuth page, it now takes you back
to the app instead of crashing
- We now save if the user pressed "Skip" on Facebook and no longer will
ask for their login data on future reauths
- Added timeouts to the DefaultHttpClients that happen after a user
interaction so they no longer have to wait 10 to 20 seconds if there is
a server issue
- No longer have issues with Facebook coming up if there is no internet,
previously it would ask for basic permissions and then have a connection
failure
- Added toast following check for survey button so that if it fails they
aren't waiting too long
