Since d8dbad0 (Highlight package requests after 14 days, 2014-06-25),
requests, which have been created more than two weeks ago, are
highlighted. This is useful because Trusted Users are generally supposed
to wait for 14 days before accepting a request. However, it does not
help to highlight requests that have already been closed. Change the
logic so that only *open* requests which are at least 14 days old are
marked.
