More Mummies

Updated Mummy NPC definitions:
The Greater Mummy Lord gets his shalore racial talents, cut immunity, a better selection of runes, and is size 3.

New NPC "Greater Mummy" an elite melee-ranged hybrid version of the other mummies. (So the GML has some poker buddies.)

Resolver filters can assign a complete object list to their base_list field.

Fixed resolver definitions for mummy wrappings so that they can be generated more reliably.

Elven ruins mummies automatically use their zone-specific object list regardless of where they're generated.
