[MERGED PR] Makes Securitrons unable to see through cloaks.

[KikiMofo]

Ive always assumed it was on purpose that robots can see through cloaks in general. AI and Borgs can so it stands to reason Securitrons could too.

Same. I don't like this change if only because the little robots are one of the few counters against cloakers that I'm aware of:

- borgs/AI
- thermals (only for HoS / detective)
- construction visualizers (due to a quirk in the engine)
- t-ray scanner (only a single tile of range)

This seems like it'd make cloakers exceedingly good.

Does clicking on a flash no longer help you see cloakers?
