MIRTH-3172: Updated the copyright date on the splash screen image.
MIRTH-3110: Fixed bug (due to switching to PDFBox) that caused owner passwords to not be set anymore on encrypted PDFs. First, content extraction (for accessibility) is now set to false, the same as it was in 2.x. Second, we're now generating a pseudorandom owner password ourselves in the dispatcher, the same way as was being done in 2.x (internally in iText).
