Before this change, we were compiling handlebars templates but then
still sometimes used the copy of compiled.js from the previous deploy,
which made zero sense. Since compiling is super fast, we continue to
compile during every deployment, and now we actually use the results
of compiling. Forcing a recompile every time avoids pitfalls like
failing to notice deleted files or failing to notice a Handlebars
upgrade.

The minify logic doesn't have an easy way to detect that you
removed a file since the last deployment.

This includes a hack to preserve humbug/backends.py as a symlink, so
that we don't need to regenerate all our old sessions.

This is a big change affecting lots of areas:
* Pipeline no longer deals with JS (though it still minifies CSS)
* A new script, tools/minify-js (called from update-prod-static),
minifies JavaScripts
* A command-line argument --prev-deploy, if passed to minify-js or
update-prod-static, is used to copy minified JS from a previous
deploy (i.e., a previous git checkout), if the source files have
not changed
* update-deployment passes --prev-deploy
* Scripts are now included with the minified_js template tag, rather
than Pipeline's compressed_js
Also, as a side benefit of this commit, our Handlebars templates will
no longer be copied into prod-static/ and accessible in production.
Unminification is probably broken, but, per Zev and Trac ticket #1377,
it wasn't working perfectly before this change either.
(Based on code review, this commit has been revised to:
* Warn if git returns an error in minify-js
* Add missing output redirects in update-prod-static
* Use DEPLOY_ROOT instead of manually constructing that directory
* Use old style formatting)
