Updated trackers list to the latest available from privacychoice.net

I've asked Jim Brock from pivacychoice.net for API details. In the meantime, here is an updated tracker list from that site. This is much preferred to disabling the highlighting of trackers completely. It's also very simple to produce this list, and no reason to have concerns over doing so until the API is made available.

Pull requests have a tendency of sitting open and unresponded to on this project. I'd love some feedback as to why this isn't accepted if that is what you choose.

Many thanks.
