Tweak search track to use QueueSong()

[dvdmuckle]

For the spc search track command, after the initial searched for song is played, related songs generated by Spotify are added to the opts.URIs variable passed to PlayOpt(). While this works as expected, the side effect of this is the recommended tracks to be played are not visible in the Spotify app. Judging from the docs for the zmb3/Spotify library, this may be remedied by instead using QueueSong(), or specifically QueueSongOpt(), to queue up at least the recommended tracks after the initial play of the searched track. Also worth testing if queueing all the songs, the search result song and the recommended songs, works in the same manner as now.

I think i have a working solution at https://github.com/ItsLychee/spc/tree/queue-tracks-fix, but I cannot be fully sure because I don't have Spotify Premium.

Nice! I can test it if you'd like to make a PR!

As an aside, that actually raises a good point about contributing to this project. I'll have to do some thinking on that.

Will do! Thanks!

Turns out using QueueSongOpt() actually slows things down and doesn't appear to cause any UX changes.
