Feature request - repeat single track

[LivBFG]

I would like to request the loop feature be able to repeat single tracks as well as the entire queue. I looked at the things linked in the other issue relating to this but I am not well versed in coding so could not get it to work myself.

This idea was addressed by #29 but was never integrated.

I can look at it again, if necessary.

That would be great!

The pull request is up... lemme know what you think.
