PHPDoc (of the public API) says that this method returns string but it also returns null, which is not allowed in some method calls. This fixes that behaviour and returns an empty string and fixes all code paths that explicitly checked for null to be still compliant.
Found while enabling the strict_typing for lib/private for the PHP7+ migration.

Since in production the SCSS files are compiled once and the javascript
files are combined once we can just as well gzip them aggresively.
This means that once they are requested and the browser supports gzip we
can just serve the gzipped file saving precious bandwidth.
