Subject: [PATCH 5/5] Include <QDebug> where the streaming qWarning() is used

Qt4's headers are leaner than Qt5's and do not drag QDebug in transitively, so
qWarning() << ... hits an incomplete type:

  thumbnailgeneratorthread.cpp:132: error: invalid use of incomplete type
  'class QDebug'

converter.cpp, dialogmultipageeditor.cpp and multipageconverter.cpp already
include it; thumbnailgeneratorthread.cpp and mainwindowimpl.cpp did not.
translator.cpp and updatechecker.cpp are left alone: their only qDebug() calls
are commented out.
