Artificer Webbing Harness examinetext and some markings fixes (#37)

## About The Pull Request
This PR does two things: clarifies the Artificer Webbing Harness'
adjustability in its examinetext, and fixes the modular longsock and
corvid markings. The modular long socks were missing hands and feet, and
this was fixed in code. The corvid belly markings were missing separate
groin sprites, and this was fixed in the .dmi.
