Kill Compass

[lvh]

Right now the Gruntfile uses compass to build. This is pointless; we're just using Sass and Bourbon right now (although quite frankly I would like to get rid of them in favor of a bunch of stuff that just runs on Node, so that I can axe Ruby out of the development process too).

This is annoying because it means we have to do gem install compass --pre right now; the regular Compass (0.12.3) depends on a Sass version (3.2.14) that is too old to support Bourbon.

Maybe this would be a good time to convert the whole thing to Gulp. I never liked that Gruntfile anyway.
