Core/Quest: Song of Wind and Water

* 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
