Spartan Reign Fix

This lightweight mod implements the smith profession system from the mod Reign and enables it for the vanilla items for Spartan Weaponry and for Spartan Shields.  The bolts and arrows from Spartan Weaponry are unchanged.  This means that anyone who tries to create a spartan weapon or shield that utilizes metal will only craft it at low durability, unless they have the smith profession.  It also means if you try to repair them they will either break entirely or be repaired at a lower durability than before, unless you are a smith.
