fix direction from coordinates
Tiefer.

Turned out that the crafting code can handle liquids no problem.

Down we go.
Working upstair & z-boundaries

OK, now you can't dig outside the existing scope of z-levels but you can
dig an upstair.  This should keep the base-builders busy for a while.

GUE: The Beginning
Bootstraps cover feet, not legs

If it's worn on the ankle, it should encumber your feet, not your legs.

This change should also make the bootstrap actually useful; it provides the same encumbrance as a pair of cargo shorts, but provides far less of everything and can't be fitted. There's no reason to wear a bootstrap if it encumbers your legs, but if it encumbers your feet you can wear it instead of socks when you don't need the warmth.
Minor punctuation and grammar fixes.

Changed the descriptions of the blowgun, slingshot, and leather sling.
Mention slingshots in pebble description.
Fix a mistake.

Re-add slingshot price.
Typo fixed: "and and"
Moving one colon on profession.json, just to make it like any other with same keyword

Now something like this can be used to grep descriptions without extra markings:
grep --color=NEVER desc data/json/professions.json | sed 's/\"description\": \"//g' | sed 's/\",$//g'
