Updated tests to match new parsing strategy.

Now we don't preserve comments, nor worry overly about new-lines.
Use a SAX strategy, rather than a splicing one.
Bumped version.
Added new built version, and added prepublish task.
Fixed behaviour of blacklisted selectors
There is no need to keep the build in git
Added better support and tests for keyframes
Merge pull request #7 from alexkalderimis/master
