Xml Parser

Using QT's XML library, I replaced the current file stream parser with an xml parser. Both Raina3D and Raytracer support the new XML model. This allows for a more standard file format that is one step closer to the Collada format. The Xml model also loads quicker by removing additional stream validation into a single xml parser.
