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.
Let's start moving towards native JS objects taking their prototype as
a constructor argument.
This will eventually allow us to move prototypes off of Interpreter and
into GlobalObject.
The output of FunctionPrototype::to_string is now more in line
with the output in Firefox. The builtin constructors have been
extended to include their function name in the output.
