Tunes up mine pedestal finale

This adds some sark wyrms and noise to the initial sinkage, as well as making the eye emit Disturbing Screams so they can find you more easily.

More to the point, the wyrms can now dig just fine thanks to a new critter tag, MF_BORES, which gives 15x the bash ability a critter which BORES would typically have.  If a wyrm somehow got to the surface, it wou wreck any fortifications you had, because it's pretty good at tunneling throug solid rock.

(Until the sun came up, at which point it'd be Screwed.)

Allow mounting Rivtech guns on a vehicle

Allow eating from worn containers / items.

Changes are:
1. get selected item via player::i_at, using only the item position, which includes worn items.
2. check the content of that item or the item itself for being food instead of duplicating that for weapon and inventory item.
3. get the it_comest pointer from the selected item as final step.
4. display message for empty worn container.
5. drop empty containers from main inventory (not worn, not wielded) if the option says so.
