Core/SpellScripts: implement Spell Proc Hooks and use it in old and new proc system
Hooks:
- DoCheckProc: executed when aura checks if it can proc
- DoPrepareProc: executed before aura procs (possibility to prevent charge drop/cooldown)
- OnProc: executed when aura procs
- OnEffectProc: executed when aura effect procs
- AfterEffectProc: executed after aura effect proced
- AfterProc: executed after aura proced and charges removed

using PreventDefaultAction() in DoPrepareProc will prevent charge drop and cooldown

default execution of a proc can prevented in OnEffectProc with PreventDefaultAction()

Now we should be able to convert almost all procs from Unit::ProcDamageAndSpellFor to SpellScripts

Notes to old proc system:
- if a proc has a cooldown we must check it in spellscript and add it when we handle the proc
- behavior with charge drops is possible undefined (use PreventDefaultAction() in OnEffectProc to notify that the script is executed)
DB/Schema: rename ip2nationcountries to ip2nationCountries (Linux)
