Rykka 5c5ac378a4 Port of Hover Inventory and Body Zone Hover Indicators. 
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.

Gifs of this in action:

Inventory Icon Overlays!

Credit goes to @ShadowLarkens for original port to Paradise and assistance with port to Virgo. Downstream port of https://github.com/VOREStation/VOREStation/pull/7748

- A note on `code/game/objects/items/weapons/storage/internal.dm`, VSCode automatically corrected the line endings, hence the massive filediff. The only practical changes are the addition of `disable_warning = 0`

Screen objects
Todo: improve/re-implement
Screen objects are only used for the hud and should not appear anywhere "in-game".
They are used with the client/screen list and the screen_loc var.
