Title: Dalaran Sewers Arena waterfall issue

Now the when the central waterfall is activated, it's done instantly, so players don't have the chance to move out of it's position.

Acording to http://www.wowwiki.com/Dalaran_Arena there's a warning before fully activating it. This warning is done with a phase transition in the Game Object activate animation.

PS: *This don't implements the knockback effect when players are near the central waterfall and it's active*
