Add a short cooldown to the traitor invisability cloaker.

[Scrumpys]

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

Flashes disabling cloaks would be a good counter. Alternatively, maybe make the t-ray scanner disable it for longer?
