Add Copy Route

[rwjblue]

As of #215 we can now copy a twiddle very easily. I would like a way to bookmark a given twiddle so that it immediately launches into a freshly copied twiddle.

Today, I keep a JSBin for every Ember version (for issue reproduction and quick testing purposes) and launch that base JSBin to get a quick clone. It would be awesome if I could launch ember-twiddle.com/<some-gist-id>/copy where the behavior would roughly be:

// app/gist/copy/route.js

import Ember from "ember";
import GistRoute from "ember-twiddle/routes/gist-base-route";

export default GistRoute.extend({
  model (params) {
    this.store.unloadAll('gistFile');

    return this.store.find('gist', params.id);
  },

  afterModel() {
    this.transitionTo('gist.new', {
      queryParams: {
        copyCurrentTwiddle: true
      }
    });
  }
}

At that point it would be trivial to store bookmarks for each twiddle that link directly to a copy...

@pangratz - I'm unsure how much work it would be beyond the snippet above. Since this builds off what you did in #215, would you wanna take a crack at it?

What do you think of ember-twiddle.com/<some-gist-id>?copy=true ?

HA! I actually had typed that first then deleted it 😝

Either way seems totally good to me.
