bug#53281: 29.0.50; wishlist: eww should handle Referrer better

[Lars Ingebrigtsen]

Currently eww handles Referrer inconsistently, I think?  (I haven't
actually looked at the code.)  I think it does send over Referrer when
doing normal clicks, but it doesn't do that when fetching images.

By default, eww should send over referrer on all requests -- if they
are "same site" requests.  (Some sites refuse to work if they don't get
the expected referrer.)  But eww should not (by default) do Referrer
when doing cross-site requests (for privacy reasons).

And there should be a way to customise this behaviour -- for instance,
to always send Referrer.
