To replace all calls to deprecated code, GTK+ 2.20 is required - add
some basic compatibility code, so that is still possible to build the
shell with GTK+ 2.18 when not using -DGSEAL_ENABLE.

With the transition to GTK+ 3.0, direct access to struct members
will no longer be possible.
This bumps the required minimum version of GTK+ to 2.20.

As of 2a78adc5e3, gobject no longer allows for setting construct-only
properties via g_object_set() during object initialization; set the
properties in a custom constructor instead.

* Rename ShellGtkWindowActor to ShellGtkEmbed, and make it require
a ShellEmbeddedWindow rather than a general GtkWindow.
* Add ShellEmbeddedWindow subclass of GtkWindow that bypasses most
of the GtkWindow complexity for size negotiation, and calls out
to a clutter actor instead; also automatically handle reparenting
the GtkWindow into the stage window.
* Use the reworked ShellGtkEmbed in ShellTrayManager, this simplifies
the code a bit, and more importantly results in the tray icons
having the correct size negotiation, rather than having a fixed
24x24 size.
