Add support for ribbon bars

[laeubi]

I recently wondered if it would be possible to have a (native) ribbon bar for SWT.

There is something for Swing here: https://github.com/kirill-grouchnikov/radiance
Also Gtk / Qt here: https://stackoverflow.com/questions/10135758/ribbon-interface-for-gtk-and-qt
Not sure about mac

I don't think the Ribbon can be native for all OSs, at least there is no such concept on Linux as far as I'm aware. So SWT might not be the best place for it. There were some former attempts to include one in Nebula, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=267015 . You may want to revive the discussion there. IIRC, it was stalled by lack of IP clearance.
