Support url dependencies?

[jedrichards]

Is there anyway to install url dependencies? E.g. dependencies that are specified just via a full url to their tarball? This is supported by npm natively I believe, and I can see some tgz download related code already in the repo. So if not currently supported, could be a quick win?

{
  "dependencies": {
    "foo": "https://registry.npmjs.org/foo/-/foo-1.0.0.tgz"
  }
}

Yes it should be easy to implement. I will put this in my TODO list.
As usual any help is appreciated 😄
