Windows version printing bug

Hello.

I just noticed that printing does not work with 1.6.3.
Further investigation revealed that this is not a bug of CyberDragon itself
but a bug of Qt framework that CyberDragon uses to do it's printing jobs.

Also another bad bug is the inability of CyberDragon to open PDF files even
if you have Adobe PDF plugin installed.

Hopefully both these bug will be fixed in next release of Qt 5.3.0 that should
come out on April.

AFAIK, Linux users should have no problems
