Draw2D touch version 2.7.1 released

+ fixing SVGFigure for IE8. IE8 expose the namespace of the SVG nodes to the tagName. In this case my code breaks.
+ ArrayList contains bug in the clone method which is visible in IE8 enviroment.
+ add css style body{margin:0} to all examples to ensure that these examples work well in IE8. The box model of IE8 and other browser differ in some points and the offset calculation didn't work.
