Add option to automatically/immediately listen when the app is opened

[AmoebaMan]

I'm using a programmable key on my phone to summon Dicio, as that's easier than using a wakeup word and doesn't necessitate running a background process all the time. It would be very cool if, upon opening, Dicio just immediately started listening rather than needing a button press.

And I don't want to have to open the DCO app to see what it found after a search, especially if I'm driving. Maybe it could read out the first one, or immediately open the browser?
