IV mutagen insertion

These add IV mutagens to the Lab chem rooms; each is comparatively rare
but the amount of them should make the odds of one or two reasonable.  I
intentionally made Fish more common because there's no renewable way to
make it, IIRC: you need canned goods.

Also makes flavored mutagens recipe-locked (so, major Nerf) and includes
recipe books for all of them, which tend to spawn in relevant lab rooms.
But if you find one on a scicorpse, that's not a bug.  Check the item
ID.  :-)

Finally, adds lab notes to the computers to keep the backstory-support
going.

Thanks for the checkup, Rivet.
IV amp-up

This migrates the nutrition & thirst effects from the JSONs into iuse,
hopefully clearing up http://smf.cataclysmdda.com/index.php?topic=4654.0
.

In the process, I made 'em a bit harsher on your system.  Try not to
take more than three shots in one session?
