Level 9 is almost done. Fixed a bunch of
    stuff:

  - blue wizzrobes (closer to the real thing, anyway)
    - fairies fly around
    - items left by enemies should be more accurate
    - the enemies' rapid-fire weapons bug
    - a double sized screen mode for resolutions of 640x480 and above
    - memory management (hehehe... I think the older versions had
      memory leaks. Hopefully I've fixed the problem.)
    - enemies stop when you get a clock
    - only one clock at a time
    - keyboard & joystick dialog box bug in high res modes
