Changes to enable Jake2 to run well as an applet inside the

next-generation Java Plug-In. Added Globals.appletMode, Globals.applet
and Globals.sizeChangeListener to be able to easily pass around the
knowledge that the system is running in applet mode, and the applet
itself, which becomes the parent container for the output. Most
changes were in Jsr231Driver to support putting the Display into a
preexisting parent container rather than a new Frame each
time. Changed JOGLKBD to allow manual initialization of the parent
container rather than obtaining it from a CreateNotify or
ConfigureNotify event since these will never be generated in the
applet case. Removed various calls to System.exit(), although strictly
speaking this is no longer necessary because it is expected that the
separate_jvm parameter will be used in conjunction with the new Java
Plug-In to create a fresh JVM instance for each run of Jake2. Video
mode switching in applet mode is working; the applet resizes (via
JavaScript) to accommodate the newly selected resolution. Full screen
mode when running as an applet is not implemented at this point, as
the intent was to show this inside the browser, though support could
be added very straightforwardly.
