Handle `@import` during CSS minification.
This meant plumbing a callback through to `compressCSS()`, which meant that
I had to alter the innards of `getFileCompressed()`. I tried to leave that
function looking more understandable than when I found it; for example, I
flattened out the nested `if`.
I went ahead and upgraded the version of `clean-css` while I was in the
territory.
