Navigate to the user's document

Futon doesn't allows this, but this would be extremely useful if by clicking on username on sidebar while user is logged in to quickly navigate to the document in auth db that belongs to that user. Some kind of profile feature.

Taken from https://issues.apache.org/jira/browse/COUCHDB-2120

Start by locating the logged-in user's username control in the sidebar and tracing how Fauxton navigates to documents in the auth database. The issue is complete when clicking that username reliably opens the document belonging to the user, with the intended profile behavior clarified.
