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.
The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().

js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

Unify the style of <delegate>.destroy() methods to only contain a
call to <delegate>.actor.destroy() and handle additional cleanup
in a _onDestroy() signal handler.

Make the event blocking done by Lightbox optional - leave it activated
when displaying the run dialog, but deactivate it when highlighting
windows in the overview.
