A little more self service in the borg chargers

[RandyArcher]

I think it'd be nice if you could load borg parts into the borg chargers. Let the borgs switch their brains into better heads, switch arms, and even go so far as to dismantle a debrained borg. This way borgs can replace lost limbs in a pinch. To be clear I think only roboticists should be able to load up said limbs and what not for availability, but overall I think a little bit more self service in the chargers would improve the borg and roboticist experience. Oh and let the roboticist make awesome human only limbs that add functions. Thanks.
