Right now showing all the pages in full is the only way we have of showing a letter that makes sense to our users. Maybe in the future we show some kind of truncated version, but the end of the first page is not a good place to truncate the letter. This commit just extracts the code for showing multiple pages from the template view, refactors it for reuse, and includes it in the send views.
