In the current stage, the action feed is the default dashboard view and it displays info related to [almost] any update to the requests the user has previously visited.
The action-boxes contain the review request id and summary, the name of the user who performed the action and the type of action performed.

Still to-do:
   * restyle the dashboard entries box
   * make the action boxes expandable and implement ajax calls to display their content

No tests yet - will start running them/ adding new ones once this is a bit more advanced.
