Recipe consistency-checking

Lain-'s point regarding the recipes being inconsistent is correct.

(Dammit.  Good catch, Lain-.)

This fixes the inconsistency: the modification now takes one charge of
thread & one rag per stocking-pair, regardless of how you go about it.
Also ensures that all recipes realize that "stockings" represents two
stockings, so you need four (plus four rags) to make 8 tentacle-socks.

Times readjusted too.  Making individual stocking-pairs and then
combining them will still be--marginally--faster, though I'll chalk that
up to better organization (not sorting through a pile of fabric, your
completeds not getting in the way of your current one, etc) and not
enforce strict parity.
