Split constructor with tons of arguments into separate setters

Also init after having connected to signals, this might fix issues where the menu won't show up the first time
an application window shows as the menu might have requested setting the window properties before we connected
to that (unlikely, but who knows).
This is in preparation for being able to fall back from window menu to application menu should the former be empty.
