Treat SCSS files changes as live CSS changes

Hey, great extension, been using it a lot lately!

This PR allows people to save scss files and just have the stylesheets reload rather than triggering a full page reload the same way css file updates happen.
Only works if you've added scss to the list of files to trigger too (livereload.exts) so it should be safe. What do you think?

Tested locally & works well.

Thanks for PR. I patched it for me, works great!
