Added more options to control the PDF-output via UI.
We are re-using the KoPageLayoutWidget (which is already translated) to allow defining the page-size (A4, Letter, Legal, Custom, etc), the Orientation (Portrait or Landscape) and the margins. The other two introduced i18n-strings are already in use in calligra/libs and therefore already translated too. The user is able now to full control produced PDF-files in the Desktop-UI and the calligraconverter commandline-application. BUG:294214
