Title: Fix support for SCSS files

- Include *.scss files in the list of stylesheet files.
- Run scss files through the `sass` interpreter instead of copying them to
the output directory like plain css files.
- Make sure the styles output directory is created first. Copying a
plain css file creates that folder automatically. But `sass` does not
create the output directory, hence if no plain css files exist then
`sass` would fail.
