Much better test now as well.

The architecture specific jobs pull it in and then build releases.

Much faster!

Closes many issues that I'll prune after adding more docs
for users.

Fixes #1581.

This was for the ssh server we removed.

Closes #1320

See #1532 for more context.

- Errored JSON requests will get back the error in JSON instead of using
  the status text. This seems better to me because it seems more correct
  to utilize the response body over hijacking the status text. The
  caller is expecting JSON anyway. Worst of all I never actually set the
  status text like I thought I did so it wasn't working to begin with.
- Allow the update error to propagate for JSON update requests. It was
  caught to show the error inline instead of an error page when using
  the update page but for JSON requests it meant there was no error and
  no error code so it looked like it succeeded.
- Make errors for failed requests to GitHub less incomprehensible.
  Previously they would just be the code which is no context at all.

Fixes #1507.

This allows external services to distinguish between them.

For #1306.

Just a login form and a list of applications. No modals or anything like
that.

Should finally be able to build with Node v12 now.

They were getting pulled from VS Code which doesn't work if you are
running a build in a clean repo.

Also too the opportunity to rewrite the build script since there was a
change in the build steps (mainly how the product JSON is inserted) and
to get the build changes out of the patch. It also no longer relies on
external caching (we'll want to do this within CI instead).

The latest version contains a fix for passing null options when reading
a file. Fixes #544.

This will be used to load extensions into the browser using requirefs.
