Title: Turns bio_memory into an active bionic.

Zero extra overhead power cost; it still works exactly like it did
before, but now you can turn it off. At high levels of skills
(particularly if you have lots of them) the constant drain of bionic
energy caused by this bionic can be a nuisance, and you may actually
find yourself wanting to let your skills rust for a bit in order to
reduce that effect.
