Continuing development new map yoking for overlays and scalar data series files.
New map yoking for brainordinate mapped files and scalar data series files now working.
Row/columns range 1..N in identification window.  Fix update of graphics and map index when yoking or file is changed.
Fixed restoring of older scenes that used OverlayYokingGroupEnum (replaced with MapYokingGroupEnum).
Small changes to file information command so that number of maps and map data is displayed for cifti scalar data file (or any file that 'has maps' but does not map to brainordinates).
