GraphUI: Promote API to JOGL via graphui.jar or within any jogl-all*.jar (WIP)

Root package is 'com.jogamp.graph.ui.gl', i.e. a sub-package of Graph denoting UI and OpenGL usage.

Implementation will stay small, hence relative files size costs are minimal.

Source and build is in parallel to nativewindow, jogl and newt
and has a dependency to all of them.
The NEWT dependencies are merely the input listener ..
