Make sure the last roster item is still added (even if it's a zombie), so that
the roster will be shown (roster is only shown when last_item property is
true).

Still to do is rendering smileys in the chat area and chatrooms.

When using show_only_online_users, roster item DOM elements are removed from
the DOM if their status changed from 'online' to something else.

When their status changed to 'online' again, they were re-added.

Their views (RosterItemView) instances however didn't listen to events anymore.

Calling delegateEvents on the view after calling $.remove() fixed this.
