Allow inserting nodes before and after result

This commit adds two new modes akin to `书社:metadata`: `书社:header`,
which supplies nodes to insert at the beginning of the `<html:body>`,
and `书社:footer`, which supplies nodes to insert at the end. Like
`书社:metadata`, these modes do not run if output wrapping is disabled.
