Summary: Fix zip file header format in zipfile.py
Initial Comment:
The zip file header unpack format uses signed longs for
those values. For the readfile function to work with very
large files (2GB+ in my case) it needs to use unsigned
longs. In the case of these files, the readfile code would
break with a memory error when trying to buffer
backwards in memory since the value is converted to a
signed long producing a negative value.
This patch converts the header unpack format to use
unsigned longs.

My bad, this patch is for zipfile.py.
Got in a slight hurry last night and didn't complete the
description well enough.
