[gutvol-d] Re: save those pagenumber references

PG needs for age numbers need to be there somewhere because without them there's no future hope for controlled/moderated text refinement. We need them to match up the canonical text with the canonical image and quickly verify that a proposed correction is legitimate. Whether the page number needs to be included in the downloaded "plain text" version, or whether the "plain text" version should be the canonical version are separate matters.
