Add facebook location strategy

  * dumb version, gives one suggestion that matches the first
  letter of user location
  * chooses from the latest foursquare response
Add test for Facebook letter match strategy

  * change FacebookLocationPlaces to
  FacebookFirstnamePlaces
  * matching the first letter of the first name instead of location
  is much more awesome
  * specs pass
Add corrected factory, tests now pass.
Fix failing tests in PlacesController
