Add Jukebox Mode (#930)

* Add jukebox mode

Songs can now be played without singing, e.g. as a break filler at parties.

- New Jukebox button in the main menu next to Sing and Party, locked without a profile like both of them
- Choose all songs, a category or a playlist, random or in order, and optionally only a part of each song (medley part, 30, 60 or 90 seconds)
- Video in full screen, lyrics without notes and a short song info whenever a new song starts
- Control bar with previous, pause, next, skip intro, audio mode (normal or instrumental), shuffle, repeat, lyrics on/off, queue and "Sing now"
- Queue with search: Enter puts a song next, Enter again plays it right away, songs can also be removed and reordered
- The queue adapts its size to the free space above the lyrics or the control bar
- Control bar and queue fade out after a few seconds without input and come back with the next key press or mouse move
- Works with keyboard, mouse and gamepad
- Smooth transition between songs, the next song is loaded in advance
- "Sing now" starts the current song with the player selection and returns to the jukebox afterwards
- The logo in the main menu is now centered
- New LyricsIcon and QueueRow textures in all Vocaluxe 2024 skins

* Fix SonarCloud issues
