Evan Prodromou 9977591b78 server-side storage model
First pass at a server-side storage model. New tables for consumers,
tokens, and nonces, with associated classes. An OAuthDataStore class
interfaces with the OAuth.php library to enable server logic.

Some additional work to get pretty-OK random number generation into
the utilities library. Use /dev/urandom if available; else use
mt_rand().
