[Multiplayer] Crucible can hit spectators, spectators get radiation poisoning

[Vetpetmon]

The crucible hits players that are spectating through other players. Was a hilarious moment in my server, but still a logic error (meaning no log output). Radiation is also applied to players in spectator mode.

Fix: Add a check to not apply a hit/damage to players in spectator. Also do the same with radiation system, have it treat spectators as creative players.

Other: Crucible attacks on players in creative not tested yet.

To add to this, schrabium revolvers also kill spectators

Crucible also can kill player in creative mode. But it's looks not bad because how we know crucible a weapon what can kill a God (Doom lore?).
