mode change of files

[Reimar Bauer]

This is more general, and I want to avoid to have all files executable

Sometimes I see after a pull request this change on altered files

mode change 100644 => 100755

Mmh strange. I see this too. Some tool of mine seems to do this. I'll see that it is fixed before commiting.

Fixed executable status of python files. Fixes issue #90
