Permit gold to be included in justpicked typeinv

Just-picked-up gold was included in the list of items in the just-picked
category for most category-based menus like 'D' or #loot, but special
handling of gold for 'I'/#inventtype (to accomodate the 'goldX' option)
caused it to be excluded from consideration as a just-picked item.
Include recently picked up gold in 'P'/justpicked when doing type
inventory, consist with other category-menu-based actions.
