loader.loadAscii and loader.loadBinary now take just one parameter with following properties:

    - model (required)
    - callback (required)
    - texture_path (optional: if not specified, textures will be assumed to be in the same folder as JS model file)
    - bin_path (optional: if not specified, binary file will be assumed to be in the same folder as JS model file)

Example use:

    loader.loadBinary( { model: "model.js", bin_path: "path/bin", texture_path: "path/img",
                         callback: function( geometry ) { createScene( geometry ) } } );
