REVISION SUMMARY
  Removed custom code inside `KJotsWidget::print`, which did the pagination and painting:
  `QTextDocument::print()` is quite capable of it on its own.
  Make Qt also responsible for margins, document placement, etc.
  
  Make `QPrintPreviewDialog` actually work: it requires to connect to `paintRequested` signal.
  For this purpose, made `KJotsWidget::print` a slot.
  
  Unify `QPrinter` creation code, add a `setupPrinter` method for this purpose.
  Note: `HighResolution` property was removed, as it results in weird-looking bold fonts.

TEST PLAN
  1. `Print Preview` works again
  2. Try to select some text and press `Print Preview` -> it previews selection only
  3. `Print` also works (tried only virtual PDF printer though)

BRANCH
  printing (branched from master)
