I have a failing build due to a `//` commenting style in [bootstrap-daterangepicker-rails/vendor/assets/stylesheets/daterangepicker-bs3.css](https://github.com/raw/jordanbrock/bootstrap-daterangepicker-rails/master/vendor/assets/stylesheets/daterangepicker-bs3.css). Possible that the preprocessor failed to render it as plain CSS?
