I've recently been adding npm audit jobs in CI where it makes sense.

The babel-plugin-django-gettext pipeline flagged a bunch of issues,

primarily stemming from two very outdated packages: shelljs and

jasmine-node. We were also using a pretty old version of babel.
This change reorganizes the build and test setup to use much more modern

tooling. We're now using jasmine instead of jasmine-node, and

@babel/register as helper to do the compilation inline instead of

needing to run babel and then jasmine from a script. We also do the

build as a single step from the package.json file instead of having a

build script.

Ran unit tests.
Built a package and verified the result.
Ran npm audit.
