-Made wizard require at least 20 players, instead of any. This is hopefully stop a low pop wizard from killing the whole crew and not calling the shuttle until an admin intervenes.

-Made nuke ops require at least 20 players. I did this because 15 wasn't low enough and it is a 5 heavily manned organized team vs 10 crew members who are just going along their own business.
-Made the spells only target living mobs. This was because the spells were listing the AI eye as a target.
