wpapcap2john: Add some sanity checks. Closes #518.
Also cosmetical fixes (license, whitespace) in WPA source files.
hccap2john: Add same extra output that was recently added to wpapcap2john
(BSSID's, filename etc) and handle multiple files better (don't abort on
error, print filename among warnings). Closes #521.
Also, support multiple entries in each file. This was a weird
limitation but it might have been due to Hashcat legacy behavior (it
initially only supported one per file). Anyways it's lifted now.
wpapcap2john: Add support for Radiotap encapsulation. Closes #377.
