Update cssjanus.js

[reedy]

Brings in minor regex changes from https://github.com/cssjanus/php-cssjanus/pull/19

Escaping differences are already present

Should we have tests?

The PHP changes aren't compatible for the js version... I guess #74 covers this difference (for now at least)

Yep. Nothing we can do at the moment. Closing for now.
