Receive users, groups and vcard changes from CS
Created add hoc commands for user, group and vcard events.
Created a vcard event dispatcher. It was previously in the VCardManager.
Moved some action code from jsp to listeners. For example, delete users jsp also deletes it's groups, now the group deletion is on a user event listener and it was removed from the jps. This was because now the deletion could be originated on the CS side and the jsp code will not be executed.
