Buildable Body scanners & consoles

makes body scanners and body scanner consoles buildable.

uses a seperate type, to prevent trolls/antags from ruining surgery with
a crowbar and screwdriver.

both the console and scanner itself can interact with it's unbuildable
counterpart, and vice versa, you can open the panel of both console
types to relink it to a scanner, with a multitool.(for example, a bomb
only blows up the scanner, not the console, you can use a build scanner
with a normal console.)

Currently there are no advantages to using better parts, but if anybody
wants to add it in the future, go ahead

Might require some better balancing for R&D levels and such.
