* Expand `/window` endpoint to behave like a proxy The `/window` endpoint was previously used as a type of proxy, but only for removing Javascript from the result page. This expands the existing functionality to allow users to proxy search result pages (with or without Javascript) through their Whoogle instance. * Implement filtering of remote content from css * Condense NoJS feature into Anonymous View Enabling NoJS now removes Javascript from the Anonymous View, rather than creating a separate option. * Exclude 'data:' urls from filter, add translations The 'data:' url must be allowed in results to view certain elements on the page, such as stars for review based results. Add translations for the remaining languages. * Add cssutils to requirements
