Subject: DRY up the colophon's content

The physical editions (hardcover, paperback) use the "extract a page from
a different book" trick to use the formatting that is unique to the
colophon. But this isn't desirable on EPUB. Previously, we needed to write
out the colophon twice: once for the physical editions and again for the
EPUB. But with this change, that's no longer needed -- both the physical and
electronic versions are based on the same source going forward
("colophon-content.adoc.erb")
