			immediately, so a headless run cannot block on a modal box that
			nobody is there to dismiss.

			This is needed because these are reachable from the command-line
			tools: opening a project written by an older QElectroTech raises
			a warning from QETProject::readProjectXml(), and with no display
			to click it, QDialog::exec() spins its event loop forever.

			The answer is chosen as: the caller's defaultButton when it gave
			one, otherwise the first "carry on" button among those offered
			(Ok, Open, Yes, Save, Apply...), otherwise the first button set.
			So the two warnings above resolve to Open and the project loads,
			which is what a batch invocation wants.
