The big new stuff is:
  - object physics completely in script language
  - key handling completely in script language
  - lots of crap code thrown out (still more to get chucked)
  - the multi-layer sprite code is working (look for @Layer in the script)
  - combined ViewPort and MainView classes (i.e. ViewPort is now a subclass
    of view, and is known as the mainViewPort)  
  - no more global 'Sprite *shipSprite', different sprites can
    be controlled/followed by the viewport.
  - implemented printf redirecting into the console, also logs _all_
    messages to stdout.log
  - cleaned up the target directories (script files in lua\ dir, all images
    in image directories)
  - added images from bapple2: explosion, flag
  - rendered some new artwork: tank w/independent turret (type 'p' and 'o'
    to turn the turret), dropship, helicopter w/ spinning rotor (yeah, i
    know the heli rotor, and tank turret arn't exactly centered, working on
    it)
