Added the ability to hunt a Wumpus.

The player now must choose an action to take and then can move or shoot at the
believed location of the Wumpus. Have also added cave names to make things in-
teresting. I think I will incorporate pits next and then bats afterwards.

Pits will be indicated by a breeze.

Bats may be indicated by a flutter of wings (haven't decided yet).

Programming is fun again! Yay! :D
