@dstftw
Is this merge request acceptable, or shall I improve something?

[kayb94]

In case you studied some of the unit tests and wondered, why the extractor is neccessary, when there already is a download button: It requires JS, which of course every user of NoScript and similar tries to circumvent.
Would be great, if this would become available for others, too (and #15873) :) If anything speaks against that, I'd be glad to hear.
I've been using the branch since March multiple times a week and it never failed so far.

Pinging @dstftw again just in case...

This extraction approach should go in the generic extractor.
