#139 override messagebox appeareances not work

[Samuel Azcona]

in the hacks section the override messagebox appeareances not work i check it but nothing happens, continue with the normally appeareance

Actually there seems a reverse bug - you cannot fully turn the hack off, resp. it's partially also triggered by another setting.

Important note: it does only apply to Qt messageBoxes, not KDE ones.
