Subject: Refactor Active Record test connection setup. Please see the
 RUNNING_UNIT_TESTS file for details, but essentially you can now configure
 things in test/config.yml. You can also run tests directly via the command
 line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection
 from test/config.yml). This will help us fix the CI by enabling us to isolate
 the different Rails versions to different databases.
