This was "npm update handlebars" followed by copying
runtime.js into the static directory and restoring the
copyright header.

There were some notable bug fixes between those versions. We are
still far behind the current version (1.3.0).
For the node stuff, I used npm update.
Then for static/third/handlebars/handlebars.runtime.js, I copied
the node version then added back the copyright.

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.
