MultiTesting

I havent worked on this in a while and im not sure what bugs are currently present.
Previously known bugs:
- double shooting
- double ammo consumption
- multiple players reloading when one reloads
- Multiple players controlling each others shooting.

Multiple player control issues should be resolved.

I believe I fixed double shooting and ammo consumption already but haven't debugged in a while.

Players should respawn fine but UI bugs may be present if conditions are met.
