Works on Igo 8.3.4

Replace only the "igo.exe" executable file from version 8.3.5 with the "igo.exe" executable file from version 8.3.4.
There is no noticeable difference between 8.3.4 and 8.3.5.

The other files (saves, content, etc ...) need not replace, this will keep all the existing configuration.
