Subject: Endianity in input files

I did some testing of *2john programs on big-endian and noticed a problem that might be wide-spread: zip2john produces infiles that can only be cracked with a same-endian build of John. That is, some of the hex fields (integers) are in machine's endianness.

This is not a huge problem but we might want to fix it (in bleeding?). I think all hex fields should be LE regardless of arch. OTOH if we change it, we break backwards compatibility on BE archs.
