Add firewall

[vrsovin]

Add a "firewall" like the netguard project, blocking the connections of all apps (user and system) that are not selected on the choose apps option.

Great idea and something we have wanted to do for a long time.

Have you tried https://rethinkdns.com/ app? It is a great firewall that integrates with Orbot for Tor proxying.
