Fix unrecognized option for 'Conversation with Muffet'

It's similar to #6 but for the desktop version

Good find.
You can add yourself in the credits which can be found in the the helpers.h file inside src folder.

Updating the executable will take a while, but I'll try to get them out relatively soon.

Done.

Looks good. I'll merge this and start working on releasing the executables
