Properly track mapping and unmapping

Browse source 
We shouldn't render a window before it is mapped (obviously), but we
render all windows in the view list. Hence, only insert the window once
it is mapped.

We could run into the case where a window is destroyed without being in
the window list, so we now track unmapping again and remove windows from
the list when they get unmapped.
