- Renamed the obj/hud other_update() proc to hidden_inventory_update()

- Renamed the obj/hud show_otherinventory var to inventory_shown
- Added the F12 hotkey which hides most of the UI except for the intent switcher, hands, health indicator, damage indicators and the other pop-in indicators on the right. The proc is called /mob/verb/button_pressed_F12(), the verb abbreviation is "F12" and it's hidden, so it won't show in the info panel. This currently only works for human mobs.
