Thar Be Less Dragons!

Let's get ready for the next big major libsass release.

A ton of stuff has been merged into libsass since the last release. libsass is starting to release tagged versions so I will update this module to fallow suit. Next version will be 3.0.0!

• Implemented new options (mainly for source maps).
• Updated and improved documentation to cover the new options.
• Added a command line utility for convenience and easier testing.
• Added full sass spec test suite which now passes 536 out of 638 tests.

Just waiting for the official libsass release now!
