Customizable script to allow players to gain honor from NPC kills

After searching the forums and finding some abandoned core mods that attempted to give honor from guards, I decided to design it as a script instead.

This seems like a big patch but it's really not too bad. Being a script it's relatively compartmentalized from the rest of the core (it does add a lot of CONF options though).

In a leaked debug version of the client these fields are named in a way that implies start, not end
float m_origin[3];
float m_originFacing;
