Prevent the error caused from GetDamageModel, add GetDamageModels.

Prevents the error caused from GetDamageModel if the projectile used on has the damage model in a behavior

Also added GetDamageModels which returns a list of every damage model in the projectile (behaviors and all)

This shouldn't cause any errors in mods even with just the GetDescendant but just to make sure I added how it was done before if it isn't null

kinda useless
