[YANKED] Do not use this version (see 1.0 notes)

• Added merging of adjacent @media rules with the same query, closing #2.

• Fixed some dimensions minifying incorrectly.
• Fixed some Eq instances.
• Improved test coverage.
• <An+B> values data type modified to disallow invalid values. This makes the data type safer, also simplifying the Quickcheck Arbitrary instance.

• Added support for @supports rules, and a slight minification for them: it removes adjacent negations, i.e.: @supports not (not ...) gets turn into @supports ....
• Test coverage was improved.
• Fixed a small bug with :lang() where spaces before the right parenthesis weren't being removed.

First release, which can be found on Hackage. The minifier already implements several techniques, both for minification, and to improve compression. It supports some basic CSS hacks (such as \9 at the end of a declaration), and most of the usual CSS features, though it lacks support for some others (for example, and ironically, the parser chokes on @supports rules).
