Cleansed Ripper Root looting fix

This fixes the looting issue with the Cleansed Whipper Root game
objects. It also removes unwanted game objects plus makes a correction
to one of the object spawned.
Elite/boss creature HP and Mana fix

Non normal level (Elite, Rare, etc.) creatures were showing with
incorrect mana and health levels.
Witherbark Axe Thrower Speech fix

The creature is using Gnoll speech when aggroed.

No records can be found of what they should say when aggroed so this fix
will stop them from saying anything.
