We wrote separate macro because if user choose to disable Gravatar then
we will not associate our application with Gravatar module which will make

'<img src = "{{ username | gravatar }}" width = "18" height = "18" alt = "Gravatar image for {{ username }}" > {{ username }} <span class="caret"></span>';
