* Added new "SuperManager" class for MySQL connections, for allowing multiple concurrent MySQL threads. 

* Implemented SuperManager inside of UserData. This means the userserver when running on MySQL will use 10 connections (+1 system connection) to handle requests, preventing the previous mire of locking resulting in singlethreadedness.
* This requires testing and grids relying on stability should not upgrade to this revision until it's been properly tested.
