BUGFIX: fixed login flow if user uses other than native credentials (e.g. uses google Facebook etc account) in SHKImgur
REFACTORING: SHKImgurOAuthView has been renamed to SHKOAuth2View
NEW FEATURE: Added possibility to feed SHKRequest with ready-made NSMutableURLRequest. Handy for OAuth2 types of requests.
BUGFIXES: SHKImgur

- added refreshToken routines
- simplified implementation (now uses SHKRequest, removed status flags - I believe that they make the code unnecessarily complicated. They are the opposite of functional programming)
- SHKOAuthViewDelegate declaration separated to special file to avoid header dependency
NEW FEATURE: added anonymous uploads to Imgur
BUGFIX: fixed authorisation flow if user revokes access
