* Fix bug that player does not have moderator priveliges when ownership was passed on to him after previous owner left the channel.
* Comment out code + alter DB field that are responsible for storing ownerGUID in the database, making it no longer possible for an ex-owner to instantly regain ownership by rejoining the channel as this is not blizzlike.
The code is commented out in case someone wants to make a configurable option out of it.
* Cleanup some other code in affected files.
