clean up
implementation of adding leadables to a non person actor
Further adjustment to the Leadable Add notification
Added Add Followers navigation links
The Add Follower link is now more elegant.
site admins and super admins can add anybody as new followers to an actor. Some limitations apply of course.
the issue preventing https links to be parsed is resolved.
added possessive object to the notification
1. added object to the notification when a follower is added by another follower or admin.

2. when people follow a group, then the story update is owned by the group, otherwise, the story is owned by the follower. That is  done for better privacy. People may not want their followers know what groups they are following. This should be overwritable by actor type. Consider this in the refactor.
com_groups now overwrites the followable behaviour for the add follower method.
actor_follow stories now belong to the group not the follower.
