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().

Did considerable work on the settings section.
Redesigned the DB to allow avatars. Each avatar image has a size and
an URL. There can be multiple avatars per profile, just different sizes.
Added accessors in Profile for avatar. Show the avatar in lots of
places, where it makes sense. Constants for avatar sizes in common.php.
