Outlines leave footer, date and slide-number placeholders out: export, RTF and the outline view

An agent run exporting a deck as an outline got the footer text and the
slide-number field (‹#›) as body lines under each title. PowerPoint's
outline view shows title and body placeholders only, so the text outline,
the RTF outline (Save As ▸ Outline/RTF) and the outline view now skip the
footer-row placeholders as they already skipped the title. Split out of the
frame export PR at review, which asked for all three together.
