Added flash fallback support. 

Flash fallback feature:

- Loader.as: added a dataParent property (flash reloads when reparenting to another DOM element, we do not want this,thus the flash fallback should only be parented once with the dataParent)
- Video.as: added a flash fallback. see FlashFallBackVideo.as. 
- FlashFallBackVideo.as: the JS object wrapper around SimpleVideoPlayer.swf.
- SimpleVideoPlayer.swf: a simple flash video player with external callback to interface with from javascript and events to catch in javascript.

methods: 
	-> 	video.load(aID:string, aURL:string, aLoadFLVAsMovieClip:bool)
	-> 	video.play()
	-> 	video.pause()
	-> 	video.stop()
        -> 	video.setLoop(aLoop:Enabled)
        -> 	video.getLoop()
	-> 	video.getId()
	-> 	video.getVideoURL()
	-> 	video.getUnscaledWidth()
	-> 	video.getUnscaledHeight()
	-> 	video.getDuration()
	-> 	video.getCurrentTime()
	-> 	video.setCurrentTime(aTime:float)		

- resources (directory): the location of SimpleVideoPlayer.swf and future library assets. 
- build.xml: now also places the resources directory into the HumboldtJSLibrary.swc.
- HumboldtJSLibrary.swc: the latest build with the flash fallback feature included.
