[MedievalWeapons] Skeletons should be able to throw francisca / throwing axe and spear

[Chribit]

The MedievalWeapons Mod adds various new weapons to minecraft. Two of these new weapons can be thrown: The spear and the francisca (throwing axe). Skeletons can hold them and use them for melee combat, but can't throw them in any way.

I'd like to have skeletons who are equipped with either of the weapons above to consider these weapons as ranged weapons if the need arises, similar to how they switch to a bow and arrows if needed.
