From Jeremy Moles, import of the osgWidget NodeKit, sourced from the original http://osgwidget.googlecode.com/svn/trunk

Notes from Robert Osfield, I've merged osgWidget trunk, and added/changed CMakeLists.txt file to make it suitable for inclusion in the core OSG, and moved imagery/scripts/shaders out into OpenSceneGraph-Data
