The body zone selector now indicates which body part you are about to select when hovered over, and the hover inventory indicator basically shows where you are trying to put an item, and then shows an item ghost in red or green, giving visual feedback as to if that item will go in the slot or not.

Ports and tweaks the Explorer gear from /tg/. Recolored to remove the mining purple, instead its now a nice blue because winter, I suppose.
Adds a new survival knife that is bootknife ready.
Replaces xenoarch GPS with budget /tg/ GPS that is more useful, as it can track other GPSes.
-The most meaning the colorable uniforms, suits, gloves, shoes, headgear, earwear, and accessories.
-Only affects mob icons for now, the inventory/floor icons still in old blend.
-Sort of a framework for possible additional options to come.
-Also messed around with some other stuff such as adding on-ear icons to the rest of the flower pins and bows, and made the base icons for the beanies lighter than the middle gray they were.
* Adds greyscale sprites for heels worn/held/on the ground. Still needs coding. First commit, hope I do it right!
* Fixed capitalization, added coding.
* Rennamed heelsheld to heels, as per anewbe's request.

Cowboy boots added (existing sprite, loadout)
Jungle boots and Duty boots added, (loadout).

A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
