Version 2.8.4 - modified preferences on the PDF file created by Fopydo

In this version the preferences on the PDF files created by Fopydo were modified as follows:

- photo albums now open with thumb images on the side by default

- documents open using default set by user in PDF reader on their computer, because users know the best option for the type and size of monitor that they are using. For instance: outlines take too much space if the PDF is opened on the laptop.
