Script http://www.wowhead.com/npc=18230/trayanise from sniff
Only the Tiny Arcane Construct appears to have fixed WP ie same waypoints repeat in sniff over and over while trayanise waypoints are different each time,
Also adds the texts to this npc
Fix http://www.wowhead.com/quest=12481/adding-injury-to-insult so it works as on retail
* Bjorn Halgurdsson unattackable until the Vrykul Insult is used on him, by setting passive + flags 2 unattackable since unlike using immune to pc this still allows the insult to be cast without getting invalid target
* It is now possible to get Bjorn Halgurdsson to Lydias Ambush without him evading as previously you could only get him as far as the water
* ensuring this resets correctly in event of evade.
* Prevent event from restarting if theres already an instance of either the Lich King, any of the 2 versions of vegard or the first 2 light's vengence objects already spawned
* Prevent further ghouls from being summoned by same npc if there is already ghoul summoned by that npc
Closes#13856
Script working, there are some issues with spell targeting for aod spells used by Lich King and Vegard to summon ghouls but this is fixed by applying the dbc hack by Rushor from original issue to limit spell targets.
Revert faction of Alliance Corpse and Forsaken Corpse to 35 as this is what it is in sniff not 1899/1900 and this was making these "corpse" npcs attack players and other npcs. Closes#13865
Revert faction of Lord Banehollow since with faction 90 using the Shadowy Potion which should make him friendly to turn in quest of npc name into him but with faction 90 remains hostile even after drinking shadowy potion, this works as should with the original faction of 1434.
* All winter veil texts for Human, Gnome, Dwarf, Dreanei, Night Elf, Troll, Orc, Tauren (Forsaken, Blood Elf and Goblin done in previous commit)
* Gossip text for winterveil for all of these
* Texts for Great-Father winters helpers once winterveil gifts event as started
