Fixes #111. Fixes issues with new facebook oauth2 library.
Fixed a typo in the requirements.txt
Fixing issues with OAuth implementation for Facebook

* Load up the FB js sdk with `oauth: true` or we're getting the old cookie
* Make sure that there's a fallback to the old `fbs_` cookie if `fbsr_`
  is not available. Granted, this won't be for long, but it broke my apps
* Added the Facebook js to the example template
* Merged in requirements changes
Removed the host redirect from the example. It kills heroku support
Updated example to include stats
