Closes #13075
DB/Locales: Correct multiple quest names for the 3.3.5 patch

Ref  #13075
Scripts/AV: Captain Galvangar updated to EventMaps
DB/Misc: Cenarion Thicket

* Add strange aura to spell_area for Cenarion Thicket (someone had tried getting the druids to cast this on themselves in sai whoever did obviously did not read this AttributesEx3: 0x00000100 (SPELL_ATTR3_ONLY_TARGET_PLAYERS)
* However even when aura is active it still would not hit druids only the Broken Corpses, found that the druids should not even have this aura (proper auras are permament feign death + blue radiation), also in sniff unit_flags2 is 2049 (we had 2048) and dynamic flags 0 (we had 40)
* Also removing stun from unit flags, this makes no difference in game as npc gets those flags from feign death
