Orbot connects directly to raw.githubusercontent.com on startup

While leak testing Orbot, I noticed that it creates a connection to raw.githubusercontent.org

https://github.com/guardianproject/orbot/blob/master/app/src/main/java/org/torproject/android/OrbotApp.java#L42

I dont know why this is even necessary as the app store updaters already provide a notification, this doesn't seem to have ever actually notified me about an update, but it sure does let M$ know who all the orbot users might be.

Maybe if it's really necessary it could make the connection over... tor?
