Keep playing current Quickmix song if new station is same

[haarp]

pianobar git as of now

When a Quickmix song is playing, and the user switches to the station this song is from, a new playlist is fetched and the current song interrupted.

pianobar should still fetch the playlist, but keep playing the current song, as it already is from the intended station.

Thanks!

I like the idea.

I think it's even better if we let the user decide whether to interrupt the song playing by a flag in settings.

Since this is limited to a very specific use-case I don’t think we’ll need a new setting. I am slightly worried about the inconsistency this creates though.
