Added the ability to include a u8 attributes parameter with all of the various put methods in the Object class. They can be omitted, in which case it defaults to "Writable | Enumerable | Configurable", just like before this commit. All of the attribute values for each property were gathered from SpiderMonkey in the Firefox console. Some properties (e.g. all of the canvas element properties) have undefined property descriptors... not quite sure what that means. Those were left as the default specified above.
