Changes

JOGL.GLAutoDrawable:
    - Add: 'public void addGLEventListener(int index, GLEventListener listener)'
      Fixes previous GLWindow addition, ie public in interface and common impl. behavior.

    - Add: 'public void invoke(boolean wait, GLRunnable glRunnable)'

    - Change: 'public void display()' semantics, in regards to the GLRunnable queue

New: GLRunnable, invoke() at GLAutoDrawable
    Allows injection of GL commands from other threads, executed after the
    GLEventListener's display() notifyier by the GLAutoDrawable.

NEWT:
    - Fix EDTUTil.invokeAndWait() and Display.enqueueAndWait() impl.,
      where we only wait for the single action/event to be processed now.

JUnit: NEWT Parenting
        - Added test cases for Swing (JFrame, JPanel and COntainer) with NewtCanvasAWT
        - Added thread calling 'invoke(true, GLRunnable)'
