listdlg.m: return Octave value rather than Java int object.(bug #41931). Make parameter list case-insensitive. Return empty matrix rather than empty cell list on failure. * listdlg.m: Use for loop to index into java array to get octave value. Use strcmpi to parse input options. Correctly return an empty matrix rather than empty list if dialog fails.
