Wingpanel doesn't set proper struts

[Danielle Foré]

In the GTK3 wingpanel, struts aren't set properly taking into account menuitem spacing. This means that depending on your theme, your windows will go underneath the panel.

Also in multimonitor setups the struts may be placed on the wrong screen

Here's some code that might come in handy (I used it in another Vala program):

Gdk.property_change(this.get_window(),
                                Gdk.Atom.intern("_NET_WM_STRUT_PARTIAL", false),
                                Gdk.Atom.intern("CARDINAL", false),
                                32,
                                Gdk.PropMode.REPLACE,
                                (uchar[]) this.struts,
                                this.struts.length);

            Gdk.property_change(this.get_window(),
                                Gdk.Atom.intern("_NET_WM_STRUT", false),
                                Gdk.Atom.intern("CARDINAL", false),
                                32,
                                Gdk.PropMode.REPLACE,
                                (uchar[]) this.struts,
                                this.struts.length);

Wingpanel now is in the same location it's struts are, though wingpanel may still differentiate in height, this still needs to be fixed
