Source: personal experience and http://youtu.be/JcOiyNaKDlg?t=18s
TDB 335.51 - 2013/02/14

Ref #8947
Closes #9077
Core/Auras: Allow auras that cannot create a separate stack for each caster to stack on one slot
DB/Creature: The Ocular

Now Eyesore Blaster hits this npc for 12600 damage as it should.
Core/Vehicle: Make the passenger join event asynchronous

Prevents a crash in the following scenario:
Player 1 enters vehicle X
Seat on vehicle X is taken by Player 2
Player 2 is removed from vehicle X
Vehicle X dismisses (but player 1 did not even finish AddPasssenger
call)

Fixes #4271
Misc/Spells:
- Add some ulduar teleport pos for spells
- Add target hack for ulduar teleport spells
Core/Vehicles: Fix crash introduced in my previous change
