JOGL/NEWT: Introduce WindowClosingProtocol (solves Bug/Request 444)

Similar to JFrame's closing behavior,
the following components window closing follow the new WindowClosingProtocol:
   - GLCanvas
   - GLJPanel
   - NEWT Window, GLWindow
   - NEWT NewtCanvasAWT

The implementation obeys either
 1) the user value set by this interface,
 2) an underlying toolkit set user value (JFrame, ..)
 3) or it's default, eg. {@link #DO_NOTHING_ON_CLOSE DO_NOTHING_ON_CLOSE} within an AWT environment.

If none of the above determines the operation,
this protocol default behavior {@link #DISPOSE_ON_CLOSE DISPOSE_ON_CLOSE} shall be used.
