Enable selection of multiple tracks in active playback queue to remove en masse.

[Dpaul]

WiiM Home - would be great to be able to select multiple tracks from ‘now playing’ queue before removing from queue.

For example, I might want to listen to only act II of a performance, and not the entire opera.

Currently I need to remove all act III and act IV tracks one by one, in order for playback to stop at the end of act II.
