#13 Removal of redundant information numbers from panes

[Craig Stuart Sapp]

When multiple panes are being displayed, the middle
cursor displays both the time in minutes:seconds and
in samples for every pane, eventhough those numbers
are identical (see attached image).

It would be preferred if there were only one set of
numbers when everthere is duplicate information being
shown for the position of the central cursor. See
the next feature request for where I think this data
should be moved to :-)
