Support a minimal/compact mode for sonixd

[jrebs]

Is your feature request related to a problem? Please describe. While the full player interface is useful and necessary for much of the sonixd navigation, I wish that there was the option to switch to a compact/minimal mode with a much simpler interface in a much smaller amount of screen space so more comfortably sit in a corner of my workspace to allow me to do simple controls without requiring all of the media library functionality of the standard UI.

Describe the solution you'd like I would like to have the option to click a toggle icon somewhere in the UI that switches the current sonixd UI between standard and compact modes. The classic Winamp application is a pretty good example of what I'm thinking of when I refer to a compact interface. It would just need to show the current track and provide controls next, prev, play/pause, stop, as well as thumnbnail of the album cover and a the usual window toolbar buttons.

Describe alternatives you've considered I've not seen any other subsonic-compatible players that have this feature, though they may exist. I have a strong preference for open source software and think sonixd is the best free player for my navidrome server that I've used so far.
