Dr. Jackson stocks mining hardware

Uses the game's inventor stock hook (his shop at night and his weekly visit
to the player's store) and his own table placement, so prices are item value
plus his markup. A rig if the player has none (30% otherwise), two basic
cards every time, advanced cards from day 10 (60%, a second at 30%),
flagships from day 30 (25%) or always during his special stock from day 20.
New, genuine cards only; only after Mining Access is unlocked. A test entry
in the dev panel (F9) restocks the counter the way his shop does.
