NLA SoC: Quick hack - Reversed playback

Animations can now be played back in reverse, by clicking on the reversed-playback button in the TimeLine header beside the play button (NEW ICON NEEDED HERE).

I'm not sure how well this works with sound, but from what I gather, this can be quite useful for animators to use.
