Portable suit sensor device

Adds a portable suit sensor console. This functions exactly like the static version, with the obvious exception that it can be carried along with you. This is intended to both make suit sensors more worth maxing (currently, I rarely see anyone using the suit sensor console at all) and to make the jobs of paramedics easier by showing them where patients are.

These devices can be found in NanoMed Plus vending machines, with a default stock of three per machine. They are fully sprited (albeit in an amateur fashion; spriting is not my forté) and ready for use.
How about "handheld crew monitor"?
