Followup to
r98583; ProofreadPage was inserting a new newline at the start of the footer on every save, but this wasn't visible until
r98583 because the previous save's newline got stripped on the next edit.
Moved the newline insertion from after to before the <noinclude>, so it's no longer considered part of the footer and doesn't expand because it hooks up to a place we *do* strip newlines at the end of the body (but is still there to make sure the footer appears on a separate line :)
