Bug on WPA1

[lynnux]

I did some tests on WPA1, it's not work, and I patched the files to make this program parse pcap files on windows, so that I can debug with Visual Studio. And by using the pcaps from https://github.com/ICSec/pyDot11/tree/master/PCAPs/EAPOLs , I finally found the problem: the 4th handshake be treat as the 2nd handshake, the secure flag is not set in WPA1. pyDot11 handle this by check the nonce, https://github.com/ICSec/pyDot11/blob/master/SRC/pyDot11/lib/handshake.py#L78, and I'v tested OK with this check.
