bug #4014 :  Load now the groups per page in the filtering panel and maintain them in a cache so that the pagination can ran more faster. Some bugs require to be fixed in the groups cache management with the filtering panel
bug #4014 :  Fix the bugs in the groups cache management and externalize it into a dedicated object. The selection of all groups is also rewritten as they can be not all yet loaded
bug #4014 :  Add localized label of 'next groups' and fix a little bug with the rendering of the next groups link
bug #4014 :  Modify the pagination mechanism: now the pagination is operated directly in the DAOs. So, a search criterion on the pagination is defined and a new list, to represent a list slice, is introduced to carry the search results matching the pagination criterion (the user profiles or the user groups)

bug #4106 :  The lifecycle of the session management service is now managed by the IoC container (Spring). In order to remove any use of the service implementation (SessionManager), some additionals methods are defined in the session management interface. By letting the session management lifecycle done by the IoC container, we can then specify specific dependency on another IoC managed beans like the scheduler. As the SessionManager depends on SilverStatisticManager, SilverStatisticManager single instance is now also managed by the IoC container. Yet, as the session management service and the SilverStatisticManager lifecycles are managed by the IoC container, they can be correctly perform their shutdown process before the JEE containers run their own shutdown process (within which the JNDI service is stopped, service that is used to fetch notification topics).
