Enhance reduce-tracking-mode

[aartaka]

For now, reduce-tracking-mode is not doing much, while it should do lots of things to fight tracking. This is the list of most trackable things in Nyxt that, I believe, we should tweak in reduce-tracking-mode (some are not tweakable yet) (based on tests from Panopticlick.):

• [X] User Agent
  • Solution: do what Chameleon (User Agent Spoofing) does or Just set User Agent it to a recent Chrome/Safari version.
• [ ] HTTP ACCEPT headers
  • Need libsoup bindings before we can do anything with it :(
• [x] Time Zone Offset
  • It's -300 (quite an unusual offset), but I don't know what to do with it.
• [ ] Hash of canvas fingerprint
  • Solution: do what CanvasBlocker does?
• [ ] Hash of WebGL
  • Is computed from WebGL canvas. Disabling WebGl should work against it, but it somewhy doesn't (#1006).
• [ ] Touch support
  • Gesture features of WebKit? Are they about touch devices?
  • Solution: set webkit-settings-enable-webgl-back-forward-navigation-gestures to nil?
• [ ] AudioContext fingerprint
  • Not really avoidable except for using a typical hardware.

Thoughts?

I was going to open a similar issue, thanks for taking this initiative!

Easy.

Should be easy since libsoup does not depend on GTK.

No idea about the rest, only trying will tell! :)
