Bind 9.11.1 (and previous)

The Statistics channel offers links to Zones and Traffic.  Both produce valid data,
but display as blank pages with a web browser.

Zones never had XSL (I provided the original implementation, but punted on the XSL).

Traffic has XSL, but it wasn't updated to reflect the split between IPv4 and IPv6 data.

I've picked up enough XSL to fix my original omission, and as penance for my sloth,
fixed the Traffic bug as well.

Patch attached.

Enjoy.
