Attaching to CSS files

[queengooborg]

Even though I know that this is a feature rather than a bug, I feel that CSS files should still have their own syntax setting, instead of being considered LESS files. This is probably a won't-fix issue, but I thought to point this out and let you guys know.

This has been fixed and we're carefully rolling it out to everyone with a pre-release along with a host of other improvements.
