tox-ify the test suite. First, this makes it easier to run since you don't

have to manually set up the virtualenv.  Second, it allows us to later create
a python3 environment for porting purposes.

Other change:

* The `mailman conf` command no longer takes the `-t/--sort` option; the
  output is always sorted.
* The ``[database]migrations_path`` setting is removed.
* You no longer have to create a virtual environment separately when running
  the test suite.  Just use `tox`.
* The RFC 2369 headers added to outgoing messages are now added in sorted
  order.
* The JSON representation `http_etag` key uses an algorithm that is
  insensitive to Python's dictionary sort order.
