Subject: Improved logging of HTTP requests - MemoryBuffer isn't seekable, so
we can't log it. Log the string instead. - Handle compressed streams - Don't
attempt to dump binary data. Either don't log it at all (if we know it's
binary), or at least convert non-ASCII characters to ASCII. - Log responses
to HTTP requests - Use the same log prefix for all of these log messages
("[LOGHTTP]"), to make them easy to see at a glance - Increased the snippet
length to 200 (80 doesn't show enough), and add "..." only if the message was
actually truncated
Resolves http://opensimulator.org/mantis/view.php?id=6949
