Implement the ECMAScript module system about boa

[Razican]

I'm working on the Module parsing now. This will probably require some changes on how we parse, since we no longer have just "scripts", we also have "modules", which require a bit of a different parsing.

Not a big deal, though. For now I will work on the parsing, and see how we go from there. I would also like to see how to adapt our tester to be able to test modules.

On the API side, I'm thinking that it would be interesting to be able to initialize the Context with a module loader, and we can provide a simple "file module loader" which would load modules from a given path. This would enable users to create their own module loader, so that they can import modules from files, databases, memory or from wherever they want.

I expect to have a PR ready during the weekend, for the parsing. If you want to see progress, check the import_parse branch.

Any updates on this? The PR was closed a while ago, and i can't find another decent, embeddable rust javascript engine like this 😕

I will soon add a project for this, it's definitely in the pipeline, along with generators and a async/await support.

Nope, I haven't got this far yet, feel free to let us know if you have any ideas or if you wanted try something out.
In theory the interpreter can run multiple times against new files

It would need to be modified to return a Value back into something else, instead of the String it returns currently

Work has started on import parsing jasonwilliams#259
