Note that Ethereal's and Tethereal's native capture file format is
libpcap format, and say that it's also used by "other tools" (tcpdump
and Ethereal/Tethereal aren't the only tools that write captures in that
format).

Weaken the claim that we read Etherpeek files to say only that we read
Etherpeek versions 5, 6, and 7 for Macintosh, so people don't conclude
that we read Etherpeek-for-Windows captures (we don't).
