Static asset compression cellcounter/cellcounter#211

In order to improve page load and load on the server, I propose we use the following solution:

Where possible, static assets are compiled with [cssmin](https://code.google.com/p/cssmin/) and  [Closure Compiler](https://developers.google.com/closure/compiler/). This allows us to generate the static assets at site build time, which improves page loads by reducing request numbers.

In addition, Closure Compiler also improves performance of JS.

This would change the method for handling deployment:

    1. update live code
    2. compress static assets
    3. reload site
