Release Haskell Stylist 2.2!

Release new Haskell Stylist & XML Conduit Stylist!

XML Conduit Stylist changed to abstract away Haskell Stylist's breaking datastructure changes.

Rewrite trivial cases of :where & :is.

This is mostly for the psuedoselector rewrites performed in Data.CSS.Preprocessor.PsuedoClasses

Implement psuedoclass rewrite rules.

Implement CSS3 counters.

Parse CSS counters.

Provide utilities for rewriting CSS-referenced URLs.

Update metadata for new repo URL.

Improve documentation, release version 1.2

Let user & useragent styles query for a lack of author styles.

Introduce simplified html2css API

Which, now that these are implemented, lowers <style> to @media & <link rel=stylesheet> to @import.

Release Haskell Stylist 1.1.0.0!

Unittest conditional styles, add loadImports API to fit Rhapsode's use.

Implement @import & @media

Dependency injection required for an HTTP client library.

Implement @document rules (save regexp() conditions).

I've still got to select a regexp library to power it.

Add bounds to all dependencies.

Normalize the license.

I decided I care more about this code getting used than whether it's aiding proprietary software.
The latter doesn't appear to be much of a threat given all other browser engines are open source.

Rename to Haskell Stylist, old name was taken.

Add additional hooks for callers:

* Resolve relative URLs.
* Set priority on any stylesheet implementation.
* Substitute content during XML Conduit traversal in place of computed styles.

Update Stylish HTML Conduit to use fixed psuedoelement handling.
