NEW FEATURE: userInfo is fetched automatically after successful authentication for sharers which can get user info.
NEW FEATURE: SHKiOSTwitter made standalone, fully using SLRequest & Accounts.framework.
BUGFIX: Indicator was prematurely dismissed when SLRequest was fired on iOS sharers. The reason: When you deal with Social.framework (most probably its ACAccount dependency, during authorisation status check), special Apple’s private UIAlertOverlayWindow is presented as keyWindow (invisible!!!). Indicator was added to this, but after firing SLRequest the window was dismissed together with indicator. Crazy bug, resolved by always presenting SHKActivityIndicator to the appDelegate.window
REFACTORING: block based animation UIView methods.
NEW FEATURE: Facebook iOS sharer is completely standalone and is using SLRequest for non SLComposeViewController sharing. fixes #223, #778, #682
BUGFIX: iOS sharer did not share pending send after authentication
BUGFIX: SHKFacebook is not able to fetch user info after successful login.
BUGFIX: when there is no user account configured in Settings.app, alert is shown.
