David Robillard 95df144967 Editor GUI touchups: 
Fixed separator lines between marker "tracks".
Fixed track alignment with track controls.
Changed track controls bevel to better fit in with canvas.
Made selected track controls colour match selected region colour (could maybe use a better colour for both though...).
Added frame to time labels to match toolbar.
