Added multiple fixes for multiplayer:

Broadsword altfire explosion can no longer damage other players
Reduced the range that sword swipes and knife throws can give Might to other players
Added player colors, which also apply to player death animations
Fixed backpacks not respawning in multiplayer games, even with respawning turned on
Reimplemented player taunts into the game
Added a custom item respawn sound
Fixed Rage of the Cosmos HUD icon misalignment
Fixed picking up RotC changing the music for every player
Scroll of Very Punching can no longer spawn alongside Backpacks, and that kinda sucks.
