Subject: Queue error messages so that a currently shown error message is not
 replaced until the user confirmed the reading. If there are no pending error
 messages and a timeout has been exceeded, the currently shown error messages
 automatically fades out as soon as the user triggered another action. This
 behavior should correspond to Ellens suggestions (I hope :-)).
