JSCS Website

For a long time we carried the idea of generating JSCS documentation website using JSDoc from JSCS rules. The first attempt was made by @just-boris here: #327.

I tried to continue developing the idea:

1. To have documentation generated from rule files.
2. To have a website about JSCS.
3. To have all that generated automatically.

So here is a bunch of `gulp`-script doing all the job.

The generated example can be found here: http://jscs-dev.github.io/node-jscs/
Later I wish we move here: `jscs.info`.
