Rewrite module

* Refactor code-style;
* Remove superfluous files;
* Remove markdown parsing (remark) from tests;
* Remove support for sanitising (use a rehype plugin instead);
* `rehypeReactComponents` > `components`;
* Remove white-space cleaning (use `rehype-minify-whitespace`
  instead);
* `mocha` > `tape`;
* `eslint`, `jscs` > `xo`;
* Rewrite documentation.
