Add new inventory functions and virtual inventories.

New functions: popen_inventory(), pinventory_holder(), get_inventory_viewers(), get_virtual_inventories(), create_virtual_inventory(), and delete_virtual_inventory().
New "virtual" prefilter for inventory_click, inventory_drag, inventory_open, and inventory_close events.
New inventory "holder" data for inventory_open and inventory_close events.
