Remove/nerf/change menders + hypospray suggestion

[Judobum]

Removing menders wont really solve the "Just hit them with this" issue. As stated even without menders medbay is still functional. Its likely it would fall into just slapping patches onto people with burn or brute. Doctors could just make a bunch of patch boxes for burn or brute in pharmacy and it would substitute for a mender with the downside of it being a bit more cumbersome if patch boxes are used or consuming a lot of inventory space if taken as single patches
