Goals:
- COMMENTED OUT: IF there is a file maintenance.html, send {root}/maintenance.html for all requests.
- If URL ends in "null", 403. Stop. # bug in mapquest js code
- If URL matches cclib, send back a 403. Stop. #(I guess these are hacking attempts?)
- If URL is /assets/*, serve from {root}/assets with gzip and max expiration date. Stop.
- If URL is /static/*, serve from {root} with gzip. Stop.
- If URL still contains one of images, javascripts or stylehseets -- log it and 404.
