Version 4.0.26-modified (2014-06-10)
	Added a lightgray-img skin based on the lightgrat skin. The lightgray-img skin uses PNG images
	(instead of a font) to render tool button icons and menu icons. The lightgray-img is a
	work-around for a bug in Webkit of Qt version 4.8.5 on OS X. Only the subset of the icons used
	in Wolfram SystemModeler is covered.
