[Feature] Tor Hidden Service

It may be fairly trivial to expose the node as a Tor hidden service (using Orbot, or other ways). These services can be created through the Orbot GUI, but there also may be a more programmatic way. Simple instructions to do this will allow users to set a phone anywhere in the world and have a node they can remote connect to. Lets find out how difficult this is, if it's even possible, and discuss best ways to integrate into install script.
