Christoph Oelckers 2a6fafa15e - don't let P_DamageMobj return negative values.
This serves no purpose, there's not a single place in the code which checks for it, but if that negative values goes unchecked to functions that expect an actually meaningful value for damage inflicted, some bad results can happen. If no damage is inflicted, a proper 0 needs to be returned so that the value can actually be worked with. The return value was a ZDoom invention, it is completely unclear why -1 was chosen if some kind of protection rendered the damage ineffective.
