SIP WG bugzilla instance

[Robert Sparks <rsparks@dynamicsoft.com>]

At the session on improving working group chair training
(and chair effectiveness), tools came up. The SIP related
working groups have been effectively using a bugzilla variant
to track document issues and help drive open issues to
conclusion.

It's available at http://www.sipwg.org (or http://bugs.sipit.net).

One point to bring forth at the beginning - we use this as
a tracking tool, not an alternative venue for list discussion.
Document/issue owners are able to make changes to a bug -
people ask the owner to add things to the tracking tool on
the appropriate list. The chairs make sure that the owners
accurately capture threads on the tracking tool.
