shell: Pass args to existing panels

Browse source 
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.
