Bug 31257: Add a new English 1 page layout to export basketgroup

This patch adds a new English 1 page layout to be used when exporting a
basketgroup as PDF. This has been modelled after an example PDF from
another library system.

To test:
1) Go to Koha Administration -> Libraries. Ensure Library A has an
address, phone and fax.
2) Go to Koha Administration -> System preferences. Search for
OrderPdfFormat. Set this to the new English 1-page layout option.
3) Go to Acquisitions. Use an existing vendor or create a new one.
Ensure the vendor has a postal address, phone, fax and accout number.
4) Create a basket for this vendor. Add a few orders to the basket.
5) Close the basket and add it to a basket group of the same name.
6) Edit the basket group. Add an address in the delivery place, and a
delivery comment. Check the box to close the basket group and Save.
7) Click the button to Export as PDF.
8) View the exported PDF. Confirm all of the information displayed is
correct.
9) Reopen the basketgroup. Edit the details and remove the delivery
place text. Re-close the basketgroup.
10) Repeat steps 7 and 8.
