Before, on Scilab backend "save as" feature, Cantor only could save the file as scilab scripts. This was occurred because the option list joins Cantor Worksheet option with Scilab Script file. I did edit the return of Scilab save extensions method splitting the option list. Now, the "save as" feature is working correctly.

1. Open Cantor;
2. Choose Scilab backend;
3. Write some command for Scilab backend;
4. Press Ctrl + Shift + S;
5. Save as Cantor Worksheet.
