item_noequip overhaul / Fixed Bug #7048

Items are no longer unequipped when disabled by item_noequip.txt, instead their effects are nullified -- however cards in them, unless also disabled, wont have its effect nullified.
Consumables will be consumed even while disabled, unless you modify the new config item_restricted_consumption_type
