vMangos set respawn time to 120 seconds for harpies and gnolls. so using that for vanilla version but I found no evidence for such short respawn times for TBC and WotLK so setting those to the standard 300 seconds.
Added the WotLK version of AV changes
- updated TBC version of AV - added patrols inside the caves - added more creatures to vanilla version.
Added gnolls, harpies and yetis to caves in vanilla AV still need to add creatures for TBC and WotLK AV version.
