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
