Scott Feeney 2c33320746 Reuse minified JS from previous deploys ...

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)
