Import py27-tinycss-0.3 as textproc/py-tinycss.

tinycss is a complete yet simple CSS parser for Python. It supports the full
syntax and error handling for CSS 2.1 as well as some CSS 3 modules:

 * CSS Color 3;
 * CSS Paged Media 3;

It is designed to be easy to extend for new CSS modules and syntax, and
integrates well with cssselect for Selectors 3 support.
