0.9.0

1. Fix missing repeat-single icon in desktop queue view.
2. Display "current / total" in now-playing.
3. Add mini-player.
4. Only show technical info in desktop bottom bar if not showing ratings, or screen width is 900px or higher.
5. Reduce CPU load when the server connection is lost, or there are no players, by using icons and not a circular spinning progressbars.
6. When getting track info for a queue item, pass its position in the queue to the trackinfo command and not its ID/URL. This helps with TuneIn stations, where the URL in the queue can change.
7. Don't repeatedly poll player status if song duration is 0 (as is for streams).
8. When parsing SlimBrowse response, if we have a mixture of items with and without images then only set image to default album or artist image for items with the corresponding type. Also, if find an item that is not an artist or album, then disable grid.
9. Remove "noselect" from browse-list, to allow text items (e.b. bandcamp URLs) to be selected.
10. Update axios, vuetify, and vuex libraries.
11. Add action to move queue from one player to another.
12. When creating a group player, also update server status 1 second later.
