Set the logger to be `AR::Base.logger` or `Rails.logger` when the gem is included to Rails

However, this will make sure that you can always change it to something else afterward.

There's currently no test for this, but after I've tried this with the `integration_test` branch, I can confirm that logs are written to `log/test.log` as it should.

Closes #581
