Combat borgs + inaprovaline nerf

Because Inaprovaline has never had any healing effects, and seems to
only artificially give the body oxygen, as a replacement for not being
able to breathe, or so it seems, since vox takes toxin damage from it

Combat borgs:
Made the cell charge it costs to use the laser 500 instead of 100, since
it gave borgs WAAAY to many shots before they have to even consider
going back to charge
Fire delay also doubled, because we don't want them to waste everything
in two seconds, and it was way quick before, still considerabily fast,
though
