Add transport support, gameobject queries, and fix item use

Browse source 
- Add setInstancePosition() to M2Renderer and WMORenderer for moving
  transport instances at runtime
- Detect UPDATEFLAG_TRANSPORT on gameobjects and track transport GUIDs
- Parse player-on-transport state from movement blocks
- Wire transport move callback in Application to update render positions
- Implement CMSG_GAMEOBJECT_QUERY / SMSG_GAMEOBJECT_QUERY_RESPONSE so
  gameobjects display proper names instead of "Unknown"
- Add name/entry fields to GameObject entity class
- Fix CMSG_USE_ITEM packet: remove extra uint8 that shifted the item
  GUID by one byte, breaking hearthstone and all item usage
- Remove redundant CMSG_LOOT after CMSG_GAMEOBJECT_USE for chests
- Show PvP enabled/disabled state in toggle message
- Relax WMO ramp wall-collision step-up check to allow walking on
  gentle ramps where floor rise per step is under 0.1 units
- Add M2 fallback when WMO group files fail to load for gameobjects
- Handle re-creation of existing gameobject render instances by
  updating position instead of silently ignoring
