Spy mode things.

[jflan17]

The implanter, as it is, destroys spy mode, as you're just rushing to implant the four best people available to gang up on and rush down everyone else that has the slightest chance of being a spy.

I haven't really thought this through too terribly much, but maybe a simple solution to this, if more drastic measures are not wanted, is to randomize everyone's names and appearance settings if it's a spymaster round.
