70-beta

* simplify ciphers

- let's not encourage (remove options 1, 2) changing your cipher suite FP
- remove "it's quite technical ..." (everything is technical to someone), trim to one line
- add test link so users can just see that it's FP'able
- reinforce not to fuck with the cipher suite in the cipher's sub-section

+We value feedback in general, but we value feedback from informed users more. There is no need for you to be an expert to participate (most of us aren't), but we hope that you at least understand our decisions before questioning them. We discuss all changes openly, and we do not make changes lightly. So, if you don't understand why we decided to add/remove/change a certain pref, search the repo. The answer is most certainly here.

+If some change we made took you by surprise (in the wrong way), remember that keeping track of changes is your responsibility. Watch the repo, read the [changelogs](https://github.com/ghacksuserjs/ghacks-user.js/issues?utf8=✓&q=is%3Aissue+label%3Achangelog), compare [releases](https://github.com/ghacksuserjs/ghacks-user.js/releases) as you update your copy of user.js, or use any other method you prefer.

- - e10s section 1100
- - privacy.resistFingerprinting alternatives sections 4600 & 4700
- - deprecated section 9999
