No Duplicated Bullets

This mod fixes a few synchronization issues experienced when playing as a client.

It fixes issues related to synchronization of cops shooting.

It prevents from generating damage that should be only done by host: in base game, if a TeamAI shoots at a cop, bullets from both host and client are accounted. Same story happens with a turret shooting at a TeamAI. This mod fixes all these cases.

It fixes cop medic healing when the shooter is not the local player.
