Player color weirdness

[BytewaveMLP]

After 1f12214da8b521c117707bc4c32a9b82d16aab4b, a couple of things were missed:

• One hanging reference to SetColor, causing player colors to be set incorrectly after a game restart https://github.com/NotMyWing/GarrysModAmongUs/blob/1f12214da8b521c117707bc4c32a9b82d16aab4b/moon/amongus/gamemode/sv_game.moon#L250
• Corpses do not correctly apply the player color for some reason.
• Ghosts do not use SetPlayerColor. Since ghosts need to be drawn transparently, I'm not sure if there's a good approach to fixing this. Could potentially make transparent textures for the (to-be-created ghost model)?

Ghost translucency is already being handled pretty fine in https://github.com/NotMyWing/GarrysModAmongUs/blob/bb3f1c4825dcd2740bcd10a1d1942336e713c792/moon%2Famongus%2Fgamemode%2Fsv_player.moon#L35-L38

Right, but that still calls SetColor, no? So it would still have the same issue as all other instances of SetColor, only less noticeable since the ghost player is transparent.
