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.
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.
Let's move towards using references over pointers in LibJS as well.
I had originally steered away from it because that's how I've seen
things done in other engines. But this is not the other engines. :^)
This adds Function::construct() for constructor function calls via `new`
keyword. NativeFunction doesn't have constructor behaviour by default,
ScriptFunction simply calls call() in construct()
This adds:
- A global Date object (with `length` property and `now` function)
- The Date constructor (no arguments yet)
- The Date prototype (with `get*` functions)
