More Elven Ear Bugfixes, Skintones Added

Made some additional positioning fixes on the elven ears and added all
skintones instead of just light; dark, dark2, tanned, tanned2 are now
all up. Still only female elven ears at this point, though; male elven
ears will be coming soon.
Changed Folder Names for Belts

I reorganized the folder for belts. The folders "belt" and "sash" under
the root folder "belt" have been replaced by "leather," "cloth," and
"metal," all with their own male/female directories as well.
Added Gender Folders to Skirts

The legs/skirt folder now has gender-specific "male" and "female"
folders as well.
