A refactoring of the joystick class to provide more

information about buttons and axes and allow slightly
easier hook-up of stanard triggers.
The events have also been expanded to include the
actual JoystickAxis and JoystickButton objects.
Changes to the JInput joystick support coming next
commit.  Android joystick stuff was modified to compile
but is totally broken with this change until the code
can be properly updated.
