Remove/nerf/change menders + hypospray suggestion

[TDHooligan]

menders are what prop up doctors and prevent it from being a miserable slog like it once was, allowing fast and quick treatment of patients who have simple brute/burn damage.

quite the opposite really, menders' first purpose was to limit resource wasting and made healing less instant.

since then the devs have balanced medbay around them, namely through:
 - balance changes to stop instant healing with styptic beakers etc.
 - making it harder for people to raid medbay into destitution by locking medicine in cartridges
 
as brute/burn healing is now mostly monopolised by the menders, it also means they can be adjusted if healing with them is too fast/slow (like how they ramp up now to prevent combat heals)
