Notify user about question dialogs

Set an urgency hint on dialog's parent, or dialog itself, when it has
no parent, to get user's attention to the dialog. For example, when
there is a changed mail composer window on a different workspace than
evolution's main window and user invokes quit by File->Quit in evolution,
then the window is waiting for a response on the composer, but there
was no hint it's waiting for anything.
