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.

Make our dev setup more similar to prod by using compiled.js,
instead of AJAX-ing templates on the fly and compiling them
with non-node code. This will make our dev environment more
consistent with prod (to avoid surprising bugs), plus it should
be faster (fewer AJAX calls).
This change also means we don't have to keep two copies
of static/third/handlebars/handlebars.js around.
