Subject: Bug 1021: Make OVR access vendor agnostic: Package
 'com.jogamp.opengl.util.stereo' contains all public interfaces/classes

Renamed interfaces:
  CustomRendererListener -> CustomGLEventListener
  StereoRendererListener -> StereoGLEventListener

New vendor agnostic 'stuff' in com.jogamp.opengl.util.stereo:
  1 - StereoDeviceFactory
    To create a vendor specific StereoDeviceFactory instance,
    which creates the StereoDevice.

  2 - StereoDevice
    For vendor specific implementation.
    Can create StereoDeviceRenderer.

  3 - StereoDeviceRenderer
    For vendor specific implementation.

  4 - StereoClientRenderer
    Vendor agnostic client StereoGLEventListener renderer,
    using a StereoDeviceRenderer.
    Now supports multiple StereoGLEventListener, via add/remove.

- MovieSBSStereo demo-able via StereoDemo01
  can show SBS 3D movies.
