Finished build system. Convert sass to stylus.

Finished build system. It now auto-recompiles and livereloads the browser if you have the extension. I put instructions in the readme.

Converted the sass to [stylus](learnboost.github.io/stylus/) due to sass's incompatibilities with node(sass is a ruby project). Stylus is very similar to node, even a bit better in my opinion.
