Miscellaneous: sro desert madman healing a zombie?

[Sundawg]

Ok, I think I've found out what goes on with them. The mummies will attack orcs on their own (and I suppose madmen). The ghouls and drybones will never initiate attacks on their own, but if they come across a Mummy in battle, they will assist it in killing the Orc(s).

I'll implement it thus.
