suggestion: do not repeat artist

[David C. Manuelda]

I have a huge collection, with several tracks from same artists (all iron 
maiden's albums, all from aerosmith...).

My suggestion is an option not to repeat artist in both dynamic playlist and 
in random when all collection is loaded.

Despite I like all of them, I don't like to hear two or more songs from same 
artist consecutive..

Could you (devs) add an option no to allow amarok to play two songs 
consecutive from same artist?
