Core/Scripts: Adding script hooks to allow for third party scripts to modify damage dealt.

Originally from the VAS Autobalance script, slightly modified.

Only addresses Spells, Dots, and Melee Damage. I'll have look at the current modules on ways of doing this but, Environmental Damage(fire/lava/drowning), Fall Damage, and Potentially AoE aren't covered by these.

Closes #7867

Core/Player: Fix build
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)
