Recently added, shop sorting, and outfit cards with T5 products

- The inventory's Recently Added puts T5 products added to the library in the last 30 days first.
- The shop's T5 listing follows its sort menu: Best Match ranks by name, Newest by upload date
  (oldest first ascending); ratings and prices (T5 products have neither) sort by newest.
- Outfit cards: outfit_products.php gets the outfit's community products added (not for sale),
  find_bundle.php is asked about IMVU's products only, and removing one in the card (remove_pids)
  keeps it from IMVU and forgets it in the outfit.
