[CR] [WIP] Expanding Contraband

This PR expand and look at the contraband item groups. I've done some
research prior to this and added some omitted contraband that are
actually quite common.
Add sharpened toothbrush

Spawn in prison contraband only.
Added soap

they only spawn in "cleaning" item groups right now.
Changed sharpened toothbrush price, weight, bashing and cutting damage and added a STAB flag
Changed soap weight to 90
Tentacle upgrade

These implement the leg tentacles as Logrin requested, and adds a damage
upgrade to the tentacle attacks.  Both are post-Threshold for
Cephalopod.
Adds razor blade
small chance of soap spawning in contraband
Digestive foundations

If you're gonna bite off a hunk of zed and swallow it, helps to be able
to eat poisonous food.
Added Extra Light Frames, Boards, and Roofs

Lighter and less durable than the Wooden frames.
Also applied XL frames to bikes, carts, and other applicable vehicles.
Added Bike "box" and shopping cart "box" (Lightweight "boxes" made from
wire)
Lowered pedal power output to reflect lighter bikes. Reverse functions
properly with cruise control OFF
Typo Fixes & Description upgrades
x-shift
Added wrapper for g->choose_adjacent.

Very useful for iuse function.
y-shift
Footgear check

As NaturesWitness requested.
Start with Albino

As requested on the forums:
http://smf.cataclysmdda.com/index.php?topic=5036.0

This makes Albino available at start, nerfs it to Pain rather than HP
damage, and includes protective gear folks can wear to prevent problems.

Later mutation does HP damage along with pain.
Tweak effects

Albino's not so bad--but again, you're wearing heavy gear or taking the
effects, and I bumped the incidence to 1/10 from 1/20...
