title: Remove "generated by doxygen" and timestamp in PDF
body: <p>As the title. I've just started using doxygen, with the first test run I noticed the PDF created has "created by doxygen 1.8.3.1" followed by the date and time, across the front page.</p>
  
  <p>Is it possible to remove this? or even just move it, say to the end of the document?</p>
  
  <p>I have noted other similar questions but only for the HTML (or RTF which Im not generating) and not PDF</p>
