* This adds separate (per map) guid sequences depending on object type
* Ported map object container from cmangos/mangos-wotlk@a2d396e
* Added type container visitor for TypeUnorderedMapContainer
* Implemented helper function to erase unique pairs from multimap containers
* Moved object storage of all objects except players and transports to map level
* Added containers linking database spawn id with creature/gameobject in world
* Renamed DBTableGuid to spawnId
* Added a separate spawn id sequence generator for creatures and gameobjects - this will be used in db tables
* Moved building SMSG_UPDATE_OBJECT - updatefields changes broadcast to map update
* Added new function to return but not increment guid
* Adjusted .debug loadcells to show low guid in map before/after load
* Added debug messages for creature spawn/destroy, for map guid debugging
* Store all Gameobjects and Creatures added to OutdoorPvP, so the callback script can be removed when OutdoorPvP instance is destroyed.
