The Help button was removed from KAssistantDialog while moving from
kdelibs4 to KF5.

The wizard dialog in KIPI plugin "Export to Flash" now has the same buttons as in its KDELibs4-based versions. Before this patch, the dialog did not have the Help button which I guess is important for KIPI plugins.

This commit added a Help button which .... does nothing. If the apps don't connect to it, the users end up with a broken Help button. I don't think it was a good idea .... but I also don't think we can fix it anymore, otherwise apps that relied on this and just called button(Help) would get a null ptr now and crash.

So, too late, but for the record, I think this was a bad idea ;-)
