Make it possible to test changes while a Polari instance is running
IRC still has strong backing in the free software community, so it is normal to have a client running while hacking. However as Polari is a single-instance application, things get a bit awkward - we have to either keep disconnecting continuously for testing, or use a different IRC client for communication.
This is clearly not ideal, so I've been playing around with options for a "hacking mode" that allows running a debug Polari instance alongside the regular instance - there's now a WIP merge request with the latest take. I'm mostly happy with it, although it would be really great to have working automatically when launched from Builder. Maybe @chergert can give us an environment variable or something we can check?
