Native (non-AWT) port of Newt to Mac OS X using Cocoa. Most

functionality (mouse click, mouse motion, mouse dragging, keyboard
events) appears to be working. Currently works with the Apple JRE and
requires the JVM command-line arguments -XstartOnFirstThread and
-Djava.awt.headless=true . Will work with the standalone SoyLatte JRE
pending additional launcher changes. Tested with Angeles demo and
various JavaFX demos.

Added -Dnewt.ws.name=AWT option to force the use of the AWT port of
Newt on any supported platform.

Known bugs:

  - While resizing a window or dropping down a menu, the application
    will hang. This is due to how the event processing is currently
    done in Newt (via Window.dispatchMessages()) and how Mac OS X
    deals with resize operations (by pushing a nested event loop into
    which we have no visibility). There are at least a couple of
    solutions. One would be to preserve the current API semantics but
    use a Newt Launcher class to move main() on to a different thread,
    saving the primordial thread for [NSApplication run]. Another
    would be to move Newt (and, by association, the JavaFX runtime
    code) to a callback model like GLUT.

  - Command-Q and the Quit menu option do not yet properly exit the
    application.

  - The coordinates for the WINDOW_MOVED event are wrong.

Added the rest of the VK_ constants to the KeyEvent class. Made
preliminary changes to support the SoyLatte JRE. Worked around
initialization order issues with Fmod.
