brick back tracking protection and set it to strict by default.

as discussed in this issue I would be pro TP returning.

@ohfp said on matrix:

my thought was to then go forth with TP and to just add a "I want no "automatic" connections" FAQ entry (and adding the entries to put in the overrides file to disable TP there, as well as a note on how to remove ublock from the policies.json as well, for the initial-start-download-thingy).

@stanzabird also seemed to agree in the above mentioned issue, despite suggesting that we keep on being very careful with the connections that we allow (which we will, I agree with him).

if you agree for the next settings release I will add this, #94 (closed) and #93 (closed). I will also take care of the faq entry mentioned above.
