A new update - Stealth ASCII

A new minor update to Stealth ACII roguelike game:
You can knockout guards by bumping into them. Each successful  knockout cost at least 10 stealth points, so make sure you have lots of stealth points before trying knocking out. Beware: each successful knockout increases the cost of the next knockout and knockout wont work if there is at least on guard in the map. Knocked out guard (Z) can also be pushed around by simply bumping into him.
