Add gadget shops to various vaults

Added gadget shops in a few places where specific "good" shops were
already being placed (mainly Orc and Vaults endings and Bazaars).

Since Nicolae's "Gadget Gallery" vault-defined shop now seemed rather
vanilla I gave it an overhaul, adding a selection of evocable armours
and jewelleries (+Inv, +Blink etc. items you won't find in a regular
gadget shop).
