[Admin / Examiner] Just one top-level dropdown in navbar - Workbench
[Very important]: Buttressed logic for updating menus on ajax-success

ajaxSuccess and ajaxComplete were not working as expected.
But it seems that the cleaner way of doing it anyways is to attach
a callback function to the $.get call

$.get is now called from within a wrapper - karo.ajaxCall(url, callback = karo.nothing)

onclick.yml -> To set the href only and not issue an AJAX call for a link, do the following:
  ajax : disabled
  url : whatever ( or specify in HAML and not here )
