Code review

This is a fake PR in an attempt to do a helpful code review of this.
So this isn't the correct way to set attributes on a model. The correct way would be to `.set` them. That way you can track what gets added to a model. This should be:

    app.user.set({
               name: username, 
               password: password,
               databaseName: databaseName
     });

Backbone supports [validation](http://backbonejs.org/#Model-validate) instead of doing the if statement.
