FSang18's Mighty Morphin' 1.3.0

Revamped XP system:
- Now You need to kill mobs rather than deal damage to them to gain xp. Different mobs have different xp values, with a catch for all other so modded mobs are compatible. Passive mobs give +1 and killing player, villagers or Iron golems while any non-Drakkon ranger will give negative xp
Fixed Black Ranger not gainin xp when being used
