* Author: Horn. Please give feedback, I tested a lot stuff, but it will be appreciated.
* One of the fixes allow all creatures to cast when being passangers, researched, this doesn't involve players.
* This basically rewrittes vehicle seat formula calculated, so it fix quite stuff that will not be visible and some eye candies: #3831 and #1984 Heart part ;) (which magically fix a lot more of it and some quests), also Yog-Sarron mechanics
* Creator Subv, (thx to Shauren also who stated that this packed should be used when researchs were started)
- You all should'be thankful, that bug was a real bitch
* Fix creatures using NearTeleportTo (example Urom in Oculus, Skeram/Viscidus in AQ and Heigan in Naxxramas)
* insert complete db sniff support, appart from missing spawns
* remove achievement from disables (supported by core - timed one)
* insert core support for spells and the defender itself, since SAI makes it act weird (maybe in future when SAI get integrated someone will convert it)
Closes#1861 on 90% (except spawns (there are enough, but a lot more needed and minnor stuff that are core side connected with vehicles spellcastresults)
Calling UpdateObjectVisibility() will make sure that the semi-far teleports (those where the destination position is not in direct sight) will work correctly.
- Shadows Fate can now be applied by more than just one player at the same
time. So on everyone who hits the unit the credit spell with the visual
will be casted on death.
- The AOE credit spells for the three infusion quests will be casted by
the boss once. If this would be done on proc, these AOE spells could be
casted up to 25 times.
-> 25 AOE credit spells plus 25 Soul Feast credit spells equals Sh**
* what happened before was spells casted from vehicle to passenger getting blocked by general check exceptions that state passengers to be not implicitly spell hit, however they should be ignored when caster is vehicle to master passenger
* fix a lot of quests that award kill credit that was blocked before
* precisely closes: #8643 and makes #5254 awardable
- some simplifications in reputation calculation
- removed aura in SPELL_AURA_LINKED should depends on SpellDifficulty
- remove some unneeded variable declarations when it's already declared
- remove some hacks
- fix some warnings in Lfg stuff
- some codestyle changes
Note: Trinity needs/wants an auction house bot in the core but for that to happen AHBot needs to be rewritten (possibly using Mango's implementation as a base)
