relative to bug #4914
changing yellowPages EJB from stateful to stateless
removing some useless code
despite Yohann's fixes, management of contacts was always buggy
So, at this occasion, code relative of contacts management have been totally modified :
- no more popups
- no more tabs
- code have moved from JSP to RequestRouter
- obsolete JSP files have been removed
Now, this app is much more maintainable and user friendly...
