	NAME: mf_main.js 
	USAGE: 

	1. enables mouse-over blur effects on buttons:

		mf_set_opacity(on, opacity)
		mf_blur(obj)
		mf_focus(obj)
		myFoggy()
		myRealFoggy(obj, way)
		myClear()
		initBlurs()
		
	2. enables liveedit mode links

		function AddLink()

	initBlurs(); needs to be called at the end of the page in admin mode!


	NOTE: some code by Margus Kohv (margus@kohv.com)
	

****** IMPORTANT!!! ******
  needs to be loaded before any else js to make this jsTextHist-stuff work!!!
