[Mailman-Developers] Patch to rotate log files and mail to owner

[Sean Reifschneider]

Here's a patch that adds the file cron/maillogs, which defaults to running
at 5am every morning.  This checks the 'error' and 'smtp-failures' files
and if they contain any information they are rotated and a summary is
sent to the MAILMAN_OWNER address.

Also added is a COMPRESS_LOGFILES_WITH option which can be set to
compress the log files (and specify what command to use for doing
so).
