This patch allows to build the widget gtk2 module along with the gtk3 one. Each module needs an extra directory and many files are shared, so the easiest way is to build gtk3 as a subdir of gtk2.

It means that old gtk2 is built as /widget/src/gtk2/widget_gtk2.a and new gtk3 is built as /widget/src/gtk2/gtk3/widget_gtk3.a.
