I know the diff looks massive (because of the generated + minified files), but don’t despair! Only the hashes changed.

E.g. the only difference in todomvc-*.js is the `version` hash at the bottom. Old version:

    version: "0.0.0+164d27e2"

New version:

    version: "0.0.0+a2ca1650"

Something is not right. tests.js refer to todomvc/architecture-examples/emberjs/index.html yet this is re-generating emberjs/source/dist/index.html:

Suites.push({
    name: 'EmberJS-TodoMVC',
    url: 'todomvc/architecture-examples/emberjs/index.html',

Good catch. That should’ve been `todomvc/architecture-examples/emberjs/source/dist/index.html` all along.

EmberJS is the only test with such a weird directory structure: `/emberjs` is pretty much empty, `/emberjs/source` contains the actual source, but the output is written to `/emberjs/source/dist`. The new patch fixes that as well by getting rid of the intermediate `source` folder.
