The Mac build seems to be terminated due to a timeout during the caching
stage.

See #1062.

Instead of doing a separate redundant build. The main problem was that
the files weren't being cached. There is probably a better way of
solving this but this seems to be the simplest for now.

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).

Travis deploy scripts can't be sequences yet.

Also, back to drafts.

- Don't error if trying to tag and the tag already exists.
- Add the build arguments to the Docker build.
- Set an environment variable for the Docker build rather than using
- the username because the username always exists (on master anyway).

* made spacing for travis yaml consistent in file

* cleaned up .travis.yml and moved some code into a script

* checking if i can get travis to build this

* travis

* fixed an if statement

* fixed travis.yml file

* replaced my name with codercom

This is so we can try out the web worker extension host.

- Implement the localization service.
- Use the proper build process which generates the require JSON files.
- Implement getting the locale and language configuration.

This is to match how the other binaries are built. Also made some
changes to make the Docker containers clean up for when you are running
this locally.
