changed handle material to single sided
Fixed regular expression so that they match better and more efficiently (without leading whitespace). None of my old VRML models could be loaded using the previous versions of the regexes.
Fixed overwriting the scene instead of adding to it in VRML loader example. This preserves the lighting and the controls, so that the Box can be spinned and is lit.
