Title: Scrobbles tracks with "artist - title"

Splits titles in the form "artist - title" otherwise it uses the username.
Fixed scrobbling on playlist sites.
Updated to newest plugin version.

I cant try out if it still works for the next soundcloud, but i think i didn't touch any code belonging to that ;)
