tsk27 Adds user's stories to private area
Adds list of user's stories to the private area of the application, 
called home in it. The structure of the list is like another stories 
lists in other pages of the application. Also the pagination system is
updated to the last version implemented on the search view. In addition,
the welcome label on the user area is included and updated from the
version that was on the template. Now it shows the user name instead of
"@user". In order to make all this new components work on the
application, a new jsf managed bean is created, calling it
UserManagedBean, because it's intended to manage the private area of the
user.
