Horizontal Scrolling - Most Popular Events
-Most Popular category now displays the top visited events
  - added field view to Content domain class
  - added function to add +1 to the views
  - when a single event is called from the controller i increase the
	counter.
  - On leftSidebarContentForSingleEvent.gsp changed g:each to display   
    the most visited events and added a contentCall() on them.
-Fixed bug that leaded to horizontal scrolling with no reason!
