Unit test for Bug 411 (Pre AWT/Swing Usage, Mixed usage with JOGL) - GLCanvas NPE fix - NewtCanvasAWT added destroy(..)

Unit test for Bug 411 (Pre AWT/Swing Usage, Mixed usage with JOGL):
    Added exhausting Pre AWT/Swing usage test utilizing a later JOGL init
    with GLCanvas and NEWTCanvasAWT.
    This works for NV+X11+Ubuntu+64bit, have to do more testing.

GLCanvas NPE fix at destroy/dispose, check if already destroyed, ie context==null

NewtCanvasAWT: Add destroy() and destroy(boolean unrecoverable)
