This patch improves NPC priest behavior.

Specifically:
Priests can now sacrifice and earn bonuses from sacrificing.
Priests can convert back descerated altars.
Priests can resurrect monsters of their alignment.
Priests of your alignment can resurrect pets.

Still todo:
Non-peaceful high priest sacrificing should yield some minions 

You will need to define PRIEST_SACRIFICE in config.h

Please send me any feedback/bugs you have!
