Title: Fix two issues with clean-css and delite-css.

This PR fix issues #274 and #275 and add better log messages in case of failure.

There is now a message if `clean-css` is not found and since it is not a critical failure, the build will continue without processing the CSS files.

There is also a message if a required CSS file is not found.
