shell: Animate window closing

Browse Source 
This provides an example of keeping a weston_surface alive after the client
destroys it.  We install a destroy listener for the resource, so that we'll
be notifified when the client destroys it.  Then we increase the weston_surface
refcount so that we keep the surface and initiate an animation.  When
the animation finishes we can finally destroy the surface.
