Do not track support

I believe the privacy behaviour of Liferea should be improved a bit. Recently I added support for the DNT "Do Not Track" HTTP header which tells websites that a users wants to opt out of any tracking. While this HTTP Header is of no use for secret services and evil companies it works with the "ethical" ecommerce guys.

Should it be enabled per default?

Now an important question for everyone: Do you prefer this preference being on per default? Firefox for example has it off per default. I'm not sure how it should be for Liferea, for myself I know I want it to be off. But what about you? If you care about this please leave a comment. Just "on" or "off" is enough!
