Title: stores lowercase email for gravatar

At the moment the starter app stores email addresses case-sensitively.
The `gravatar` api requires them to be [lowercase]/https://de.gravatar.com/site/implement/hash/), so I changed the `mongo` settings to store email as lowercase. This avoids wrong results for emails (unintentionally) inputted with some uppercase characters.
