This introduces a node.js package called @beanbag/frontend-buildkit,

which is a utility package that brings in dependencies for Babel,

Rollup.js, TypeScript, and LessCSS.
Going forward, our products will depend on this package for static media

building. This gives us a versioned set of dependencies that we can

easily reference by any codebase, and in the future a single place for

any plugins or configurations needed.

Used this package to build static media for Djblets 4 and Review Board 6.
