Disable Self Explosive Damage

Prevents players from dying to their own grenades and rockets. Note that if you shoot enough rockets (around 15/20) you can still kill yourself. This also doesn't prevent players from killing themselves when they hold a frag grenade in their hands.

You can add iprintlnbold(iDamage); at the beginning of cancelDamage() or any other variable found in cancelDamage() to debug it (see attacked player, attacker, damage, weapon used, damage type etc.)
