Reorganized using roots

- split up the index.html file into css, js, and html (closes https://github.com/cheeaun/life/issues/10)
- use Jade to concat all the files together properly... might use it for some other things too.
- add a license (closes https://github.com/cheeaun/life/issues/17)
- compile everything into a single html file (closes https://github.com/cheeaun/life/issues/35 and removes the need for ajax requests)
- deploy to github pages with 1 command (thanks to roots)
