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.

Rework psuedoelement infrastructure so they can be their own boxes.

Add support for psuedoelements/classes.

Improve code cleanliness to avoid future bugs.

Add method to override CSS inheritance.

Parse HTML 'style' attributes.

Fix parser freezes, blocking issue for Rhapsode.

Ignore invalid selectors.

Aid attribute sorting, fix install of internal modules.

Fix cabal file.

Switch to new namespace for consistency with other modules like css-syntax.
