Draw accelerator in Palette SL #3459

The accelerator in the primary information in the Palette
has not been drawn because there was not enough space
reserved for it. The preferred size we get back for the
Palette window does not include the accelerator of the
Gtk.AccelLabel. We need to include that in our calculation for
the Palette size.

In order to make that information available which is part
of the Palette class we need to pass the instance to the
PaletteWindowWidget instance.
