Bug 11856: Add publication year and edition to English acq PDF templates

To test:
- Switch OrderPdfFormat to pdfformat::layout3pages
- Create one or more  baskets with a few orders, make sure you
  are adding some records that contain a publication year and/or
  edition statement
- Close the basket
- Create a basket group
- Print the PDF and check that edition and publication year
  show up and bibliographic information is printed correctly
- Switch OrderPdfFormat to pdfformat::layout2pages
- Repeat PDF print

This patch also changes the formatting a bit and differentiates between
UNIMARC and MARC21. For MARC21 no additional punctuation is needed as
those are cataloged with the information. Only spaces are added for MARC21,
while UNIMARC is kept they way it was before.
