Feature: Display Tor onion URLs in the dashboard and choose which service to exposes

[louneskmt]

• Display Tor onion URLs in the dashboard, maybe a tab or modal in the Settings page, so the user doesn't have to connect to the dashboard via Tor to get apps onion URLs. The dashboard onion url is already exposed in the Settings page.
• Allow the user to choose which app / service to expose via a Tor hidden service, for example with a check list in the Settings page (modal?). By default, all apps can be selected.

Thoughts on this mock-up? If interested, I can start working on the implementation. Let me know either way, thanks!
