Bastien Nocera 876d41b141 shell: Pass args to existing panels 
When re-activating the same panel, we could destroy and recreate the
panel, or better reuse the panel, and set the new argv
(usually to switch pages).

Since we're changing the "argv" property of panels to not be construct-
only anymore, we reviewed the panels for potential memory leaks as well.
