Fix #3069, and consequently #3374, #3378.
A new filtering class has been created: "static extended filtering".
This new class is an umbrella class for more specialized filtering
engines:
- Cosmetic filtering
- Scriptlet filtering
- HTML filtering

HTML filtering is available only on platforms which support modifying
the response body on the fly, so only Firefox 57+ at the moment.

With the ability to modify the response body, HTML filtering has
been introduced: removing elements from the DOM before the source
data has been parsed by the browser.

A consequence of HTML filtering ability is to bring back script tag
filtering feature.
