We apper to spell it "TShark" rather than "Tshark", the fact that it's
"Wireshark" rather than "WireShark" nonwithstanding.

Say we run on NT 4.0 rather than "NT" - I don't know whether we run on
NT 3.x (and 2000/2003/XP are really NT 5.x and Vista/2008 are really NT
6.x - that's why Microsoft are talking about "Windows 7" as the next big
release).

In the capture-privileges paragraph, note that it's dumpcap that needs
to run as root, and suggest not only that Wireshark shouldn't be set-UID
root, but that it shouldn't even be run as root, and that the same
applies to TShark.

Update "How to Report a Bug" to reflect that we're telling people to
report bugs on Bugzilla, and that "wireshark -v"/"tshark -v" give almost
all the version information we want.
