Details:
This changeset changes the inheritance structure so that the LzApplication class (containing user code) does not indirectly inherit from the as3 Sprite class. Sprite has data members 'x', 'y' (and several others) that would otherwise pollute the user's application namespace and prevent the use of these as variable names.

However, a Sprite-inherited class is needed as the top level class that is executed in the flex program. The solution is to leave LzApplication in place as the 'holder' for user code, but to create the LzApplication from a barebones Sprite-inherited class,
    that we call 'LzSpriteApplication'.

    The barebones generated class is this:

      public class LzSpriteApplication extends Sprite {
         private var app:LzApplication;
         public function LzSpriteApplication() {
            app = new LzApplication(this);
         }
      }

and the LzApplication/LFCApplication constructor gets the sprite and makes it
    available for use as needed.

Tests:
    SWF8,DHTML: smokecheck, weather, lzpix
    SWF9: hello, weather, lzpix, application reported in LPP-6781
