Maplers' Well-known Battlegrounds

Fulfilled merge of Drago's AriantPQ PR #438 into the source!
Adjusted MCPQ map limits predicted within battlefield's map info node.
Added max number-of-players option when creating a AriantPQ lobby.
Added party creation check when trying to create one inside the AriantPQ rooms.
Adjusted several AriantPQ mechanics, in order to either improve the existent features or make those that was still unavailable work seamlessly (score update, ariant batlle points).
