Perhaps this is causing the output buffering issue with the arm builds.

To make installing as a PWA possible. Fixes #1181.

For #1306.

Should make language packs work again.

I temporarily removed this during the refactor so it needed to be added
back. This time I bundled it with the nbin loader code since it's all
related (will also make it easier to remove).

- Add VS Code icon
- Trim dashboard to just display dedicated VS Code section
- Version was getting unset during build
- Add back nbin shim which I temporarily took out earlier
- Update tests for log level env var changes

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

This is mostly for development where VS Code might not have finished
compiling yet.

This fixes the case where the script is killed before all the
dependencies were fully installed.

They aren't used in subsequent files and just slow down CI since it has
to extract from the cache and then package the changes.

Fixes #1087.

Fixes it not being included in the optimized build as well as making it
more consistent.

This matches how the rest of the build is organized but also hopefully
solves an issue where the VS Code directory is empty because we try to
cache it directly and Travis might be creating it.

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).
