Harmony modules

[dherman]

Adds a prototype of Harmony modules to the interpreter, when in Harmony mode (./njs -H).

I have one concern here. In Zaphod, I'm relying on the noPropFound hook to give me a way to look up elements from the HTML. Here is the Zaphod snippet just for reference:
Narcissus.definitions.noPropFound = function(name) {
var value = content.document.getElementById(name);
if (value) {
return Proxy.create(Zaphod.createElementHandler(value));
}
else return undefined;
}

I might be able to do the same thing without it, but if possible I'd like to keep that hook. (On the other hand, if we decide to remove it, we should also get rid of it from jsdefs.js.)

Same note here about noPropFound.

Maybe say why, if the token is blacklisted? Could be a followup. It'd be nice to say "modules aren't allowed because you aren't in Harmony mode".

[pcwalton]

Here too.

[pcwalton]

Just use an object or an array lookup, perhaps?

[pcwalton]

Might want a comment here saying // global, module, or function frame

[pcwalton]

no {}

(def.type === IMPORT_DEF)

[pcwalton]

Not sure what this is for…

[pcwalton]

Could you add a comment explaining what x.type !== EVAL_CODE is for? My brain hurts :)

This rocks.

Maybe "mixin"?
