Merge branch 'Rel19' of https://github.com/mangostwo/server into Rel19
[Core] Beginning the implementation of the Dungeon Finder's Queue
System.
Still very rudimentary and needs much work.
*Small update to prior commit about pet despawns.
[Core] More updates to queue system.
* Currently the queue system is ~30% done in implementation, ~90% done
* in planning. The ability to find other players/groups and send
* everyone into an instance should come soon.
[Core] Implemented most of the framework needed for finding compatible
matches in the dungeon finder queue.
[Core] Mostly finished with queue compatibility code.
* Just need to implement a function to merge compatible groups/players.
