[Feature Request] Kill all playback/caching as soon as the stop button is pressed

[awsms]

Currently, Tauon will hold the playing state for a remote track (for example on a sshfs mount, airsonic), which will cause Tauon to freeze if the track wasn't entirely cached when the Stop button is pressed. It's verifiable as you can't play another track when Tauon is in this state, untill the said track has been entirely cached, and Tauon can't be closed either.
So if my network connection is temporarily interrupted, I have to manually kill Tauon.

Do you still have this issue on 7.9.0+?

Could be a dupe of #449
