HiDPI issues with KDE applications

[Christoph Cullmann]

Hi,

I just checked again the HIDPI support of Kate/KWrite on Windows and it 
"sucked".

It seems we never properly did setup the stuff to auto-scale, e.g. the

  QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling, true);

call was missing, we only had the

  QCoreApplication::setAttribute(Qt::AA_UseHighDpiPixmaps, true);

part that we sprinkled in most of KDE's things in the past.

I now rectified that for Kate/KWrite, shall we do this for all our 
applications?

Greetings
Christoph
