Lets the new blood filter tool be put in medical belts/medical aid kits since those are supposed to hold surgery tools
Lets spray bottles, amputation shears, and surgical tape be put in medical aid kits since it's supposed to hold the same stuff as the medical belt (I didn't add the plumbing stuff to medical aid kits though since chemists don't get them)
Removes bio bag and chem bag from the medical first aid kit since they're too big to go in there anyway
Adds blood filter mode to the debug omnitool since it's supposed to have a mode for every tool define
* Renames a few variables. Also reorders fallback order again.
Renames item_state to inhand_icon_state
Renames mob_overlay_icon to worn_icon
Renames mob_overlay_state to worn_icon_state
worn_icon_state/mob_overlay_state now never gets used for inhands.
* Fixes some comments
* Fixes map issue
* Restart lints
* Properly resolves conflicts
