QtFRED dialog title

[Goober5000]

From PR #6322:

The "qtFRED v24.1.0" suffix is only really needed on the application title bar, not the title bar of every dialog.

Unfortunately it's not looking like this is possible

I did a bit of searching and found other coders looking for the same thing:
https://forum.qt.io/topic/55613/solved-why-is-every-dialog-title-appended-with-application-name/8
https://stackoverflow.com/questions/43563746/show-qapplicationapplicationdisplayname-only-on-main-window

It seems like such a simple thing that can be controlled by a flag, but I can't find a flag for it.

Digging further, I found the original change:
https://codereview.qt-project.org/c/qt/qtbase/+/29254

So it looks like the application display name is used only for this feature:

For compatibility reasons, the app name is added to the caption only if setApplicationDisplayName() was called -- or if the caption would be completely empty.

This is good. In that case, just set the main window title and don't set the application display name.

Edit: there is a flag in the original code submission:

WA_NoApplicationNameInWindowTitle

But it looks like that flag may have not been included in the ultimately-merged change. It's worth trying first though.
