Add miscellaneous minor cleanups to prepare for the introduction of

Yred's injury mirroring: move the routine to make a visible monster 
flash a particular color into its own function, add an integer-based 
square root function based on Newton's method to stuff.cc, and adjust 
prayer lengths for Zin (1 turn), Yred (20 turns), Ely (same as Yred), 
and all gods who ignore prayers (same as Zin).
