Adjusting readme path to work correctly for stylus

I haven't changed the README for less and sass, but the root path into `components` needs to go into the `typeplate` folder for stylus, which I presume is also the case for SASS and LESS. I'll test those out and send out another patch when I'm sure that's the case. I removed the compass line, because stylus doesn't have compass (there are alternate frameworks like `nib` for stylus, but I don't think we need to add extra stuff if its not needed.
