LESS!

I think I set up the less --> css pipeline the way we will want it for the rest of the project. It works by compiling everything in the manifest.less file in src/styles/less to the src/styles/styles.css file, which I added to the test pages (hopefully doesn't cause problems with the mocha css, if so we can get rid of it) and the discovery.html page. With this setup it's easier to make big changes to bootstrap in the ads-variables file, basically make our own custom bootstrap, as well as add our own css in ads-custom (which for now I am not adding because it is kind of haphazard).
