Armor percentage rollover

In versions of Doom prior to 1.2, armor percentage was not limited to 200. Since the armor count in the status bar has only three digits, the display can wrap around to 0 percent if enough armor bonuses are picked up.

The true maximum for the armor percentage is probably defined by the static limit on lump size in a PWAD; a map can contain only so many things, and therefore only so many armor pickups.
