Title: iOS 5 support

Fixed a bug where any app using this SDK would crash on launch due to the existence of ACFacebook* attribute strings. Resolved it by wrapping these in logic to ensure they're only in iOS 6, and also replaced the attribute names with local strings. Kinda sucks, but i couldn't figure a way to support iOS 5 otherwise.
