Ignore speed effects when adding hero power cooldowns
Added cooldown_hit to statblock, prevents players & enemies from being stunlocked due to fast/consecutive hits pushing them into the on hit animation.
Moved enemy sfx_hit out of block testing against hit cooldown

Configurable restyled NPC dialogs
