Adds generic implant and known_cybernetics to adv medscanner

[Delams-The-SM]

About The Pull Request

Adds generic implant to loadout you can give custom name to, it will show up on adv medical scanner for that extra RP, makes any implants one might have in their medical records A REALITY !!!

For easier implanting of those generic (and in the future others ???) implants the currently avabile tracking implanter in loadout has been split into a empty implanter and a loose tracking implant for the same combined price as before.

Additionally gives adv medical scanners ability to detect common cybernetics like razor boy/girl upbringing claws.

And yes /obj/item/implant/excelsior still properly shows up as death implant on adv medical scanners.

Actually now that I am thinking about it, would making the tracking implant cost 1 and implanter's 0 be better ?
Would still make tracking implantation's cost be 1 while letting someone have the generic implant for free (since it serves no purpose besides medical records and RP)
but then there would be a free implanter (even if empty) in loadout

For more cybernetic few perhaps 3 implants rather than just one would be useful
