Changing filenames from Greeklish => Greek (subprocess complain)

[Νικόλαος Κούρας]

Please and tell me that this actually can be solved.
Iam willing to try anything for 'files.py' to load propelry.
Every thign works as expected in my webiste, have manages to correct pelatologio.poy and koukos.py.

This is the last thing the webiste needs, that is files.py to load so users can grab importan files in greek format.
