Makes the Publication model act as an activity; overloading the default ActivitiesController#index view in the Bibliography Plugin in order to differentiate Publications from the other event types.

* Known issues:
** route to /activities is not working (only to /activity);
** publication cache needs to be implemented in the model, not in the helper;
** when a publication is added to n projects, n events are created (all with the same content).
