Fixed: a player's PWO settings weren't cleared properly if the weapon's weight was zero upon closing the game.
When Zandronum closes, any weapons whose PWO weights aren't zero get saved into the "PreferredWeaponOrder" section in the user's config file. However, if the weights are zero, but weren't before, the old weight still remains in the config file. So, when the user starts up Zandronum, the weapon will have the old weight again.
Checking and removing the weapon's old weight from the config if its new weight is zero fixes this issue.
