Add a short cooldown to the traitor invisability cloaker.

I'm sure people go for TK a lot less often now that you can't grab a camera monitor and murder the entire station with impunity; does that mean TK needs a buff?

Just for the record, TK saw a colossal nerf not too long ago that changed the functionality entirely. So arguably, yes.

It's also worth noting that no one's complaining about the TK nerf, or at least not as vociferously as this whole cloaker debacle.
