Surgery synchronisation!

Hilights include grammar fixes in the messages, complete integration of
mechanical heart (nanopaste>screwdriver>>>bonegel) surgery (eyes remain normal),
use of kits for organ surgery (advtraumakit>tajarabruisekit>>>>gauze), and
reattachment of heads for cloning.

It was easier just to do a mass copy than to try to make proper per-commit
applications - thanks Yinadele and crew!
