Medical fixes (and a PDA thing)

The PDA diff prevents detomax carts from working when the messaging server is off.  Everything else looked the same except the default size.

Medical synchronisation is the big one - peridaxon (slowly) fixes internal organs, and is made by combining bicaridine and clonexadone in plasma.  No message added - figured that was your project.  Surgery sync includes the use of traumakits/tajarapoultices, nanopaste on mechhearts and head-reattachment.

It compiled fine, but I didn't set up a test server because mrgh.  At least reverting everything's simple enough if needed, right?
