WW-1349 MailReader: Move the current mailreader example to the sandbox, as an alternative example, 'mailreader-wildone' (one execute method per class with wildcards), and replace it with the wilcard-version of 'mailreader-bang', which uses multiple methods per Action class (per the usual practice).
