fix instance of array problem

[akjava]

if method need Array or Object parameters ,and in inside it is using instanceof to parameter,it make a problem.
i heard some frame problem is there.(maybe linker option fix this problem)
for example in JSONLoader.js ,if url is object never called console.warn.

THREE.JSONLoader.prototype.load = function ( url, callback, texturePath ) {
var worker, scope = this;
if ( url instanceof Object ) {
console.warn( 'DEPRECATED: JSONLoader( parameters ) is now JSONLoader( url, callback, texturePath ).' );
