[svn] Send AttackStart package when update visibility.

Update DoMeleeAttackIfReady to support dual wield.
Show player modelid2 instead id3 of triggers. This should fix the bug that gameobject::castspell summon a human model.
Remove the correct flag to make creature attackable. This should fix the bug that Illidan and Magtheridon are unattackable.
Add NullCreatureAI for trinityscript.
Fix channeler's soul transfer.
