Renamed Shoulder Hair, Fixes, More Sub-Categories

Made a number of fixes I found on the page. Fixed name of the Yellow eye color. Fixed constraint for Tiaras so males cannot use them. Renamed Shoulder Hair to Left Shoulder w/Braid and Right Shoulder w/Braid. Added sub categories for Shoes, Cloth Belts, and Metal Belts. Also fixed url in README.md; it was broken.

This should cover everything else for now. I committed the fixes for the shoulder hairstyles to the main repository along with a quick fix to some of the ears on the female elven ears sheet.
