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.
