[NEW] Printouts (worksheets and handouts) headers, footers, and more

[oscarlevin]

The latest version of the PreTeXt-CLI has just be released (version 2.36.0).  If you have any printout divisions, namely <worksheet> or <handout>, you will now see some new options in the Print Preview view:

1. If your exercises have hints/answers/solutions, you can now turn these off or on in the print preview.  Note that you might want to refresh the page after toggling these so the content reflows to the pages before printing.
2. You can now print headers and footers, for the first page, the remaining pages, or both.  These can be edited in the browser (just click where you would expect on the left/center/right of the header/footer region).  What you put in those headers will persist across the entire book.  Hopefully useful if you want to always have a name region or the course name.
3. As a publisher, you can set the default value for the headers and footers in the publication file.  Documentation will soon be available here: https://pretextbook.org/doc/guide/html/publication-file-common.html.
