omniauth fails to accept callbacks directly from foursquare

[cjjuice]

callbacks currently must be initiated through omniauth and pass a state paramater to foursquare to authenticate. However with the connected apps platform, users have the ability to add the app without visiting the app's site first.

This causes the callback to fail because omniauth did not make the first call in the sequence.
