#544 Show link number in MatrixEditor status when multiple segments selected

[musewhirl]

When the MatrixEditor is opened on multiple segments, a wheel allows the user to select which segment has focus. As the wheel turns, at the bottom status shows the segment track and label. However, it does not show the link number for linked segments. So, when the wheel is turned, if the track number and label are the same, there is no way to determine which segment is selected.

A new feature could be added to allow the link name to appear in the bottom status bar along with the track number and label, just like it currently does for the track label on a segment. There ample space for it.
