FR: Shuffle all albums

[ktims]

The "All Tracks" page has a "Play random" button which adds random tracks to the play queue.

I would like to see a similar feature, but maintaining the integrity of albums as the unit of work, instead of songs. It would behave the same as the "Play random" button on the All Tracks page, but add some random albums to the queue instead. It'd be even nicer if this behaved like a 'shuffle' of the album library and continuously kept the play queue alive instead of 'add n random albums' (less repetition).
