JS cat and minify on all pages

[andyreagan]

need a good strategy for non catted, non minified JS for development, then minification for testing, and finally pushing minified to production

in the django .html templates for, example, maps.html, there are a bunch of JS includes. this is great for adding new features with just page reloads to test them
in books.html, the JS is catted together. this adds another step when writing new code
in index.html, everything is catted and minified. page load better (but the lions share of the loading is the data...but again that is async), but very slow for development (the minification takes a few seconds)
