Play Druid against an opponent

Let the computer move according to the following:

if (winning moves)
  choose one at random
else if (non-losing blocking moves)
  choose one at random
else
  choose any legal move at random

The computer won't play very well but it should play correctly and detect 
wins and losses. To improve computer play try to build a path from one 
side to the other, perhaps by extending your longest path. Remember Druid 
is 3D so use lintels to break opponents paths and extend yours.
