Filter excluded tags within the section map builder
Because we need might need excluded tags to build compare links, the section map generator needs to have access to those tags. But, we don't want excluded tags to have section headers. So instead, we'll create another copy of the list that doesn't have tags excluded. Signed-off-by: Tom Duffield <tom@chef.io>
