FileFuzzer

While going through the OSCE course, I have created a number of fuzzing templates and files.  One that comes in handy, the python file fuzzer I made.  It is not mind blowing, but I have found some overflows with so it is nice to have for me at least.

# Kind of basic and wordy, but hey it works for me....
