set new document window as parent for dialogs during load

and exit typedetection early and completely if application quits
while detecting

During typedetection, before loading proper, we have the hidden window as
parent so warnings are not modal to existing windows and they are cancelled on
exit.

Once we do have a window, then reinit interaction handler to have that window
as the parent for any further dialogs.
