Import Handlebars compiler and dependencies

Storing these in Git seems kind of weird, but seems to be [1] the done thing.
I have to say, it's a lot more appealing than getting 3 packages from npm
installed globally on every prod and dev machine -- we already have too much of
that with 'pip install'.

We can upgrade these in the future by running 'npm update' in the repo root
directory.
