commit a627afad7b69ff3757fb791921d78281ad94c68b
Author: Matthew Finkel <Matthew.Finkel@xxxxxxxxx>
Date:   Wed Nov 14 17:36:53 2018 +0000

    Bug 28051 - Integrate Orbot and add dependencies
    
    Also:
    Bug 28051 - Launch Orbot if it isn't running in the background
    
    Bug 28329 - Part 2. Implement checking if the Tor service is running
    
    Bug 28329 - Part 3. Remove OrbotActivity dependency
    
    Bug 28051 - Stop the background service when we're quitting
    
    If the user swips away the app, then initiate quitting as if the user
    selected Quit from the menu.
