Fix, NSMatrix -deselectAllCells

[Georg Fleischmann]

Hi,

here is a patch for [NSMatrix -deselectAllCells] to set the selected  
row/column of an empty matrix always to -1 (even if in radio mode empty  
selection is not allowed).
This is needed to have the correct starting point after a renew, since adding  
a row does not check whether the selected row/column is within the allowed  
range.

Best wishes,
Georg

        * gui/Source/NSMatrix.m [NSMatrix -deselectAllCells]:
          set _selectedRow/_selectedCol = -1 for an empty matrix,
          even if empty selection is not allowed.
