Target Mailman onto the Storm <http://storm.canonical.com> Python ORM. This

enables a few interesting things:

1. It makes it easier to do our "pillars of storage" idea, where list data and
   messages could live in one database, but user information live in a
   separate database.

2. It reduces the number of moving parts.  SQLAlchemy and Elixir can both go
   away in favor of just one database layer.

3. No more Unicode/string mush hell.  Somewhere along the way the upgrade to
   SQLAlchemy 0.4 and Elixir 0.4 made the strings coming out the database
   sometimes Unicode and sometimes 8-bit.  This was totally unpredictable.
   Storm asserts that if a property is declared Unicode, it comes in and goes
   out as Unicode.

4. 'flush' is gone.

One cost of this is that Storm does not yet currently support schema
generation.  So I cheat by dumping the trunk's SQLite schema and using that as
a starting place for the Storm-based schema.  I hope that Storm will
eventually address this.

Other related changes include:

- SQLALCHEMY_ENGINE_URL is renamed to DEFAULT_DATABASE_URL.  This may still
  get changed.

Things I still want to fix:

- Ickyness with clearing the databases.
- Really implement multiple stores with better management of the Store
  instances.
- Fix all the circular import nasties.
