Movement sighted

The player has been able to sort of move prior to now, but now we have a little more functionality.

Supported movement direction keys are: Arrow Keys, WASD, and HJKL.  Additionally, there are key modifiers:  CTRL+Key to always attack that creature.  ALT+Key to not attack that creature.    G or ',' to activate the elevator.

I'm not at all sure about inventory management yet.  I may need to dedicate tomorrow to that.
