Title: Update Koala to reflect recent FB Change

Facebook [recently changed](https://developers.facebook.com/roadmap/completed-changes/#december-2012) the way OAuth codes are handled such that each code can only be redeemed once, which breaks apps that were parsing the cookies each request (previously the suggested approach).

This pull request adds notes in the code to highlight this change, and deprecates the now-useless OAuth#get_user_from_cookies method (which didn't return the access token). Along with a change in the [OAuth wiki](https://github.com/arsduo/koala/wiki/OAuth) this should point app developers in the right direction.

Note that this does not provide a solution to how to store the cookie; while I'd be glad to link to a good approach, it's outside Koala's immediate scope.
