Bugfixes. RosterItemView didn't rebind events. Undefined vars in onConnect.

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.
