Smaller release, but fixes a big issue that's been prevalent since 1.0.0.
fixMaterial()
This function runs after node creation, but any objects with WorldGridMaterial or the GREY materials will be replaced with the appropriate material for that object.
WorldGridMaterial is something created by the pskimporter addon that this script uses. It is used when either an error occurs in the material finding process, or when it cant locate the material. With the new function, this fixes that.
