New medical items

These are a few new medical items. A few Issues, I ment for medical tape
and gauzes to serve as a replacement for duct tape and rags
respectively. Disinfectant currently heals like bandages and doesnt
remove infection. None of these items have spawning thingys for them
yet, if any one could solve these problems I would really be thankful.
Medical items updated

This is the medical items updated to have some more uses gauzes act like
rags when used, disinfectant is now basically first aid (made a little
rarer).
