Option for Disabling Multiplayer Items (Weapons, Powerups, etc.)
When true, disables the spawning of things that are flagged for multiplayer only. This would allow users to play co-op without having high-tier weapons early on to make the game more balanced and challenging.
This commit explicitely disables multiplayer things in coop only, using sv_spawnmpthings.
