[Openid-specs-ab] Dynamic Client Registration

I've incorporated many of Nat's design choices into the OAuth DynReg 
document and have posted to the OAuth list for feedback. This includes 
use of RESTful HTTP verbs and the link structure for communicating the 
endpoint URLs. I also incorporated some of his editor's notes which also 
came up earlier on the OAuth list, including JSON-in.

I left in a method to do rotate_secret, pending discussion on the 
functionality. It parallels the client_update function in many ways.

I would encourage everyone to read over the new DynReg spec before the 
OIDC call tomorrow.
