games: add xchomp

Xchomp is a game closely patterned after Pac-Man(tm) that runs under the X
Window System, with several different mazes added.

This is strictly a keyboard-controlled game. The arcade game had very simple
controls -- one four-directional joystick. In xchomp, all control is through
the arrow keys.
