Introduce a temporary neutral brand for tiles because it was driving me nuts

when testing Ely's pacifying. (Currently only inappropriately reuses TILE_NEW_STAIR, which will have to be replaced with something more distinctive some time.) Also add an option for colouring neutrals on the minimap (defaults to red, like hostiles) and allow secondary item use by Ctrl-L-clicking on items in inventory (firing weapons, unwielding rods, etc.)
