LoFi not hiding when Spotify is closed

Good to know this project not abondoned! Im read #68 Maybe change behavior of this function. For example then Spotify have paused state, not closed. It is possible? Maybe then it will work.

I think that hiding Lofi when it does not detect Spotify is a mistake. There should be a message that states that Spotify must be running in order for Lofi to work; people often mistakenly think that Lofi is a spotify replacement (sadly, it isn't).

Note that if Spotify is paused, Lofi should still be displayed but the cover art will be blurred.

Will be addressed alongside #256
