Zach: This was necessary because we need to do some further refactoring before
and sky app can *be* a mojo app. This is basically a short-term back door. If
you prefer a different name, just suggest it.

Please fix the long line. 80 char max for Dart code.

I need to take a closer look at what this is for, but if we keep this for the
time-being, there should be a big scary comment explaining why it's here, that
it shouldn't be used, and a TODO for removal.

Done.
