* This covers all that involve main quest mechanics npcs + awarding quest
* However 2nd effect of http://www.wowhead.com/spell=48059 needs to be scripted, it is supposed to spawn a lot of guids - it's the event
* It closes the problem in #4552, however event remains so leaving it open, I won't spawn them
* 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)
- 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
* drop off c++ script of Clintan Dreamwalker ID: 22834
* convert quest_end_script of 10964 to SAI
* rewrite and add bigger event support
* add a checker to his summon so the spirit script can trigger event alone (I didn't try to rewrite next quest...)
Closes: #8689
* it needs to trigger reindeer transformation used by Fresh Holly, while has a side core check already handled. This needs to happen in the same time and not after.
* traced the auras are same from sniffs and the mechanic
* now Fa-la-la-la Ogri'La should be completeble for all (tested all normal cases)
Closes: #4333
* cleanned a bit and edited old @Treak fix, credits go to him, the quest will* work 100% blizzlike when target_unit_master #8643 gets a fix for vehicle. What concerns the quest is done. I've already fixed the core kill_credit issue, but needs to be discussed.
* leaving the vehicle_AI until they get integrated correctly to SAI, this can be easily converted after. Currently need to make some hacks to make it work close to good if using SAI. (specificly terrain acts weird at that place)
Closes: #5424
