Change the import syntax to a more friend and customizable way

[LukeXuan]

I've changed the syntax of import to

  [service@]font_or_id_name[@version][#timeout]

And should support all Typekit modules.

Also I added the registry key to the package.json, absence of which causes the original package not to work here.

This I assume is an oversight, and should either be removed or changed to something more generic, like systemjs-font contributors. If we include everyone here, which is another good alternative, I think it will become stall fairly quickly.

[LukeXuan]

Well that's my fault, going to correct it in the next commit.

[LukeXuan]

Modify to all contributors listed in github and generic authors appended. It was my fault to add only my name on it when I want to complete the package.json. Please forgive my offense.

[maxnordlund]

No worries, I've done this myself.

[maxnordlund]

Changing the format will break existing code, and should be avoided if possible. If however this doesn't do that I'm ok with this. But please add, not remove, tests for both formats to ensure this.

[LukeXuan]

Changing the format was my original propose, since It's hard to understand the original format from the test.html for me. And for the same reason I cannot support both format:(

[LukeXuan]

Maybe I'll contribute more time on the original repository and this pr I will close.

That not so good, let's pull in @guybedford to hear what he has to say. (Maybe I'm just being paranoid and we should bump a major version)

[guybedford]

Thanks for the PR. Plugin contributors are very much in need. How about [service:]font_or_id_name[@version][#timeout] for the syntax? Ideally I would actually like this plugin to be entirely a third-party project. @LukeXuan if you'd like to keep it at your own repo, I'd gladly deprecate this one for that.

@guybedford I originally intended to use that one. However I find that the address I receive by System.import("google:Open Sans") in an HTML file differs from that received by import "google:Open Sans". So I changed it to @

[guybedford]

@LukeXuan I've updated the URL polyfill implementation in SystemJS to properly support google:x style URLs so they don't turn into google://x. This will be coming in the 0.19.21 version of SystemJS later today. Let me know if that might work for you here then?

@LukeXuan Thanks, it works.

So, does this PR become official system-font?
