In an effort to make the way our sprites are organized make a little bit
more sense, this takes ALL the sprites in `icons/clothing` and moves
them over `icons/obj/item/clothing` or another appropriate file in the
case of non-clothing items.
A lot of these files had to be split since they lumped everything into
the same dmi which had to be changed since people, reasonably, expect to
find a hat in the folder named `hat` and not in the one where we're
supposed to keep uniforms in.
A lot of smaller files were also merged into already existing dmis where
it made sense.
Lastly, all the colourable items kept in `icons/obj/item/clothing` were
updated to the new palette. Those items were:
**Backpacks:**
- GD Sacred Icon
**Belts:**
- Fannypack
**Gloves:**
