! bunch of spawn reworks !

[sapphonie]

• draw 386x386x386 unit cube around spawn before spawning, find another spawn if there's enemy projectiles or enemy players found in it, avoids spawning players into dying immediately
• wait in spectate / death cam to spawn players instead of respawning -> sitting in spawn -> teleporting - reduces getting flashes of your actual spawn room before immediately getting teleported
• Soap now requires gamedata for the above change
• Soap now requires sourcemod 1.11 or greater
• players are no longer targeted by sentries in dm
• Soap will no longer waste processing power checking if a spawn is clipping into the world or not every time it attempts to spawn a player, instead it checks when loading the map and removes it from the valid spawn list then
