Python 3 sucks

The third version of FIOC ( Python3000 for you cheese lovers ) is kind of lame, even lamer than classic FIOC. Minor changes suck and bigger ones weren't necessary.

no more using Python to fix filenames after, e.g., unzipping a file that came from a system that used a different encoding
if your unzip utility is broken, you should fix it once instead of fixing the filenames everytime you unzip something.
