Bug 1247: Align NEWT AWT driver w/ GLCanvas (not fixing any issues)

Bug 1247: Enhance JAWTWindow DEBUG output (not fixing any issues)

Bug 1247: JAWTWindow fail early w/ useful info:
setAWTGraphicsConfiguration(..) if awtConfig is null,
getGraphicsConfiguration() if awtConfig is null

Bug 1247 - TestGearsNewtAWTWrapper fails AWT recreation case
removeNotify -> addNotify, e.g. by moving to other monitor
AWTCanvas removeNotify didn't cause 'local' destruction of the NEWT
window, allowing a 'recreate' w/ subsequent addNotify.
This case has been hacked-into NEWT.AWT.WindowDriver + AWTCanvas:
 - suppression of window destroy events
 - keeping fields/states intact in NEWT.AWT.WindowDriver
 - propagating signals appropriately
Note: This is barely a working hack and not a fine piece of software :)
This AWT backend driver exists only due to historical reasons.
This hack simply proves that JAWTWindow works properly.
