A little more self service in the borg chargers

[Clarks]

Quit being dorks about it. It takes and id and two different tools to even be able to add a limb to a borg (id > crowbar > screwdriver). It confuses people who don't have experience with the job - even broken borgs often can't guide people through the steps to replace limbs - cut it down to a single tool or roll it in with removing a borg's powercell (id > crowbar).

That said, also adding easy customization through a dock would be great for the vanity of our mechanical jerks.
