Make loyalty implants let you see other implanted people

[AleksAdamska]

Basically just give loyalty implants the sechud functionality of being able to see who else is implanted. I find that a lot of the frustration and apathy behind being a regular (non-rev, non-sec, non-head) crewmember in rev comes from not being able to tell your allies from your enemies aside from sec, and so having a way to do this without having to get conscripted or when you've run out of sechuds would be good, I think.
