Adjust: Allow repeat in combination with shuffle

[photovoltex]

This should allow to combine repeat and shuffle without any odd behaviors. Shuffling itself was quite a bit inconsistent before, so I had to adjust the shuffling a bit so that's a bit more predictable to work with.

@aome510 could you give this a try and see if there is anything weird in the combination or how the queue behaves? Thanks in advance :)

Fixes #1550

Great! @photovoltex no pressure but if you're OK to merge, then by all means do, and we can release v0.7.1.
