Allow formatting of now playing

[denolfe]

Describe the solution you'd like

The format for now playing is currently <song> · <artist>. This caught me off guard as most other applications do <artist> · <song>. A setting to be able to adjust this would be great.

Additional context

Great project, extremely useful. Admittedly, I tried pulling the code down to try and make a PR, but I wasn't able to get it to build.
