add #genocided command

Comparable to #vanquished, be able to view info normally available
during end of game disclosure while the game is still in progress.
The new #genocided command lists all genocided and extincted types
of monsters.  Unlike #vanquished, there aren't any sorting choices.

Potential future enhancement:  provide a way to view the genocided
list at the "what do you want to genocide?" prompt.
