Request adding the specular in the colladaImporter

I discovered the specular attribute isn't apply in the collada importer.

Could you add this code in the method "processPhong(phongType pt, ColladaMaterial mat)" in the class "ColladaImporter".

// set the specular color value of the material
if (pt.hasspecular()) {
// set the shininess value of the material
if (pt.hasshininess()) {

have fun :D

Thanks.  This is now in cvs and svn.
