Remove/nerf/change menders + hypospray suggestion

[Dhaidburt]

I've honestly ran into the same thing as botany, making patches or other healing medicine and medbay just.. does not care. I think your efforts could be better used elsewhere, such as sending out patches to other departments who may need it or just in general. They don't have menders, and depending on the map they could be too far away from medbay to heal up before they die.
