Port over Hover Inventory and Body Zone Hover Indicator

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.

Inventory Icon Overlays!

Credit goes to @ShadowLarkens for original port to Paradise and assistance with port to Virgo. Sending to Polaris ASAP.

- 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`
