This version addresses Jim's comments, reorganizes the draft somewhat to 
put all the syntax changes in one place, and makes one significant change.

SIGNIFICANT CHANGE: Only RSA signatures can use key fingerprints.  Since 
an eddsa key is 256 bits, and a SHA-256 fingerprint is also 256 bits, 
there's no point to eddsa fingerprints, so I took them out.

If there is an actual problem that eddsa fingerprints would solve 
("symmetry" isn't a problem), let me know.  Otherwise I'll leave them out 
since we now have less code to write and verify.

R's,
John
