- Refactor `config/dev.exs` to use `config/dev.secret.exs` instead of
fetching the SMTP information from the environment and using hardcoded
database credentials. This is useful when different developers have
different database credentials and they use different SMTP adapters
- Add a sample `dev.secret.exs` in `config/dev.secret.sample.exs`. Also
gitignore the origin `dev.secret.exs` file
- Add instructions on how to setup the config file for development in
`README.md`
- Add `Plug.Swoosh.MailboxPreview` plug on "/mailbox" route in
development mode for easier development with e-mails
