Serious unicode issue on Python 2.7 with subprocess.popen

[ChristianTremblay]

gitExec function doesn't work anymore with folder having unicode caracters in them

There's also a few lines missing specific unicode encoding/deconding to 'utf-8' (like the os.walk function to browse directories)

Probably problems due to Python 2.7

I had a similar issue, but running gitcheck with python3 avoids them. Might be worth changing the shebangs of setup.py and gitcheck.py to #!/usr/bin/env python3.
