Add new random playlist

[StarWolf]

I use it every day, thank you for the great player that I think there is no competition, even among paid. Add another random song selection mode: no tracks are selected randomly in advance (creating a random list), and every time you play the next track, and that was a function of playing only one list, without "lists in order" and "lists by accident." Forgive me for my English, it is not my native language.
