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:**
- Gloves
- Single Glove
**Hats:**
- GD Cowl
- GD Cube Hood
- Furred Crown
- Surgeon Cap
- Kippah
- Plain Hood
**Shoes:**
- Konyanger Gomusin
**Coats:**
- GD Eccentric Coat
**Uniforms:**
- Colourable Dress
- Shortsleeve Dress
- Evening Gown
- Open Shoulder Dress
- Assymetric Dress
- Tea Dress
- Long Sleeve Dress
- Colourable Scrubs
- Colourable Jumpsuit
Refactored hitby to be in line with TG's version.
Refactored item weight defines to a more clear naming scheme, also in
line with TG's version.
Refactored how the movement bumps are handled, ported signals to handle
them, in preparation for the movement update.

Items do not push other items anymore if they are tiny.
