Title: Enter key play pause

I added play/pause function to the Enter key (in all the editors) . It's not as useful though on LMMS if your music is depending heavily on samples/loops since sound files and arpeggios won't start in the middle but it's still a practical/common key assignment and it behaves like the GUI play button.
