Scripts/Utgarde Pinnacle:

- Re-write Svala Sorrowgrave
- Scripted achievement The Incredible Hulk.

This script was writen basing on work and data:
- Original TC script.
- Albis fix for Arthas sounds and texts https://github.com/TrinityCore/TrinityCore/issues/4002 .
- Ric event start fix.
- Recorded encounters uploaded on YouTube.
- Data found on ScriptDev2 forums.
- Iov's custom SD2 repo and Svalas's script https://github.com/Iov/scriptdev2 .
Also thx to:
- ZxBiohazardZx for pointing how to fix looting problem when boss is killed when flying.
- Aokromes for confirmig how many times event "Ritual of the Sword" is performed.

- Mini event with Arthas.
- Call Flames: timers of cast and time between "Ball of Flame" (48246) can be wrong (based on videos).
- Ritual of the Sword works  and is performed once at 50% hp but:
  a) Still need retail data for teleport position of Svala floating above player.
  b) Need fully fixed spell Ritual of the Sword (48276), the triggering of spell Ritual Strike - Trigger Missile (48331) part was hardcoded.
- Spell Paralyze (48278) used by Ritual Channeler: fixed stacking and selection to ritual player only.
- Achievement "The Incredible Hulk": works but often Scourge Hulk don't get initial dmg from spell Ritual Strike (spell 48277 Effect #1 Value: 6650 to 7350).
- Looting problems when Svala was killed in air (require vmaps and option "vmap.enableHeight = 1" enabled in "worldserver.conf").
- Moved script_texts to creature_text.

It require option "vmap.enableHeight = 1" to work properly.
