main, lightbox: Fix lightbox for zoomed windows

The correct way to make an actor having the same size as another is
a ClutterBindConstraint. Connecting to 'allocation-changed' fails because
the allocation might not change even when 'width' and 'height' properties do.
This is the case of Main.uiGroup, used as parent container for zoomed
window clones.

In lightbox.js we bind also the position because in principle it could change,
even if currently only fullscreen lightboxes are used.
