FRAMEWORK UPDATE: Facebook SDK 3.14.1
BUGFIX: login and logoff now works properly. Also it is possible to download user info without uploading item first.
REFACTORING: removed pending connections. Each sharer should encapsulate just one upload. So if you want to upload multiple items at once, fire more sharers instead complicating the sharer.
REFACTORING: Now sharing works properly even if user removes the app permissions on Facebook
DOCUMENTATION: updated Facebook settings info in DefaultSHKConfigurator
BUGFIX: fixed minor maxVideoDuration check error
BUGFIX: logout now also deletes user's video limits
BUGFIX: removed obsolete method from SHKFacebook header
