Added some code to make finishing the OpenID login work.
Changed the OID storage so that there's a "canonical" URL and a
display URL. This is because of i-names, which is annoying.
If the login succeeds, we try to find a local user associated with the
canonical URL. If they don't exist, we let the user either create a
new account, or login to an existing account and connect to it.
A totally unrelated change is that the DB engine now uses InnoDB.

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.
