[Scilab-loc] Double value and single value in gui.pot

[Yung-Jang Lee]

If we ever trace the code, (for example GUI\sci_gateway\c\sci_delmenu.c)

------------------------------------------------------------------------------------------------------
      // Unset a Menu a Scilab Graphic Window
      if (VarType(1) != sci_matrix)
        {
          Scierror(999, _("%s: Wrong type for first input argument: Double
value expected.\n"),fname);
          return FALSE;
        }
      GetRhsVar(1, MATRIX_OF_DOUBLE_DATATYPE, &nbRow, &nbCol, &stkAdr);
------------------------------------------------------------------------------------------------------
'Double value' always maps to 'MATRIX_OF_DOUBLE_DATATYPE' which means 'real
or complex matrix' in Scilab. (Memory representation of
variables<http://wiki.scilab.org/Memory_representation_of_variables#head-d64767f239049822afbdf1e6ffb433173b03d777>or
http://wiki.scilab.org/Localization_in_English_-_Standard_messages
).

But if we follow the gui context then 'Double value' seems to  mean 'a real'
(I don't expect to read any complex value in GUI applications).

The use of 'Double value' causes trouble in interpretation of the meaning,
especially if coupled with the use of  'Single value' which means 1x1
matrix.

To avoid mistake, use 'a real' if it really need  a real, 'real matrix' if
we need a real matrix or 'real or complex matrix' if we need a  generic
data.
