Add a MillControl Folder for nano

[Steffeeeen1234]

We should insert a millControll Folder for nano, too. In that case all the things which need to be changed, e.g. for the PINs are already changed and the user can just download the file.

It would be better if there is some config file or so, but the easy way is to copy the folder.

this will be done with a config file. see issue #24
