This is a squash of the original branch It also contains fixes/rework from Albert Astals Cid If you're interested in its history have a look at the gsoc2018_digitalsignature branch The poppler dependency situation is: * With 0.51 you get most signature information * With 0.68 you also get signature location/reason information * With 0.73 you also get signature certificate information
