REFACTORING: simplified photo sharer

- got rid of custom error message as it would have to be translated to all languages - hopefully from this point of view the generic builtin message is fine
- simplified positive callback, as ActivityIndicator UI should be always called by the delegate
REFACTORING: fixed excessive header dependencies. ShareKit should compile faster now.
BUGFIX: added SHK.h to ShareKit.h - it is needed for flushing offline queue.
Add close button on Vk OAuthView.
SUBMODULE UPDATE: Facebook-ios-sdk
REFACTORING: shareKit core library moved to ARC
REFACTORING: removed unnecessary curOptionController nilling - now it is weak property, it nils itself automatically on dealloc
