Input outline fixes

Fixed input outline colour.

^{On a side note, you should probably include compass in your gemspec since it's required. Or better yet, remove the compass dependency altogether and use asset pipeline. :)}

I appreciate these commits, but it would be nice to have a PR without so many whitespace changes.

I didn't add Compass as an explicit dependency, because I wanted to leave open the possibility of making a Sass plugin as well. If it's causing problems, you can open an issue (or PR) for adding it as a dependency.

Not everyone using Compass is using Rails, so I don't think the asset pipeline is a consideration for providing Sass or Compass support.

Thanks again!
