Add a short cooldown to the traitor invisability cloaker.

[Dauntasa]

The cloaker is one of these things. It's an item which has exactly two hard counters on the entire station, one possessed by a whitelisted job, the other possessed by a job that has no less chance of being traitor than anyone else.

this only became accurate after they took away sec's thermals and then made flashes not disable cloaks
