Title: Don't use sharers which are defined in defaultFavoriteXXXSharers but in SHKSharers.plist

This allows to exclude sharers by removing them from the SHKSharers.plist. Also it avoids the situation where SHKSharers.plist contains a subclass of a specific sharer but defaultFavoriteXXXSharers returns the base sharer class.
