Removed node-sass-middleware as a dependency

Code: Updates libsass to v3.0 and sass-specs

Update test runner to match sass-spec

- The sass-spec runner by default looks for `input.json` and will skip
  any test which doesn't have one. Mirror that behaviour by skipping the
  test run if an `input.json` file doesn't exist.
- The sass-spec folders have been moved around so update the ignored
  folders to match where the todo tests now live.

Code: Updated to latest master and fixed a test

Added some more keywords to package.json
