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

[Sylvestre Ledru]

Hmmm, after a quick look with Vincent C. (who is also on this mailing
list), we realize that, yes, 'MATRIX_OF_DOUBLE_DATATYPE' is badly
choose name in the source. It is causing confusion in the code. 
We are going to rename it to something like
MATRIX_OF_REAL_OR_COMPLEX_DATATYPE
Any comments on this?

Yep, we are reading all messages (you can imagine how sexy it is) and
changing thme.

PS: I c/c the dev mailing list since it is border-line.
