Wishlist: add a "single play" playlist option

[thegreyshadow]

Thanks for making termusic. I'm using 0.12.1 now.

I use it most for listening classical music.
When pressing the 'm' key, one can cycle between playlist loop, single track loop, or shuffle.

I would like to request an option that would play the entire playlist once. Is that possible?

Thanks again.
