[FIX] web_tip: better event handling

* Override message_fetch from mail.Thread in a dedicated limk module (mail_tip)
and fire an event when the messages are loaded. This is necessary for tips on
the chatter.
* Override render_value form web.form.FieldStatus: Call reposition() when a
FieldStatus object is done rendering.
* Tip.reposition() method
* Handle web bus resize event
