Feature request: Bring back the Tor toggle in settings

[lateralvoid]

In past versions there was a toggle in the settings to disable Tor routing. This is necessary to be able to use it on any OS that already forces all networking through Tor (such as Tails and Whonix, arguably the most anonymous OS choice available today).

I suggest that this toggle is re-instated, with clear warnings that Tor shouldn't be disabled unless using the Tails or Whonix operating system.

Ideal behavior would be for the app to recognize when it's installed in Tails/Whonix workstation, and automatically disable the Tor toggle such that the user doesn't have to go searching for it upon a connectivity error.
