Reported by Yann COLLETTE
-- Bug description --
It's not possible to send string parameters via the opar structure of an xcos block to a block of type 4.
To be able to send strings to a type 4 block, I must use ipar and transform the strings into scilab code via str2code.
A better solution should be to put these strings into an opar list and get these strings via something like GetOparStringPtr (like the functions found in modules/scicos_blocks/includes/scicos_block4.h).
