automod: show matched text in summaries; don't use show post date in summaries; add logMessage variable to alert action
Post date will always be more or less the time the log message is posted. The logMessage variable in the alert action contains the full, formatted log message that would be posted in a log channel as the AUTOMOD_ACTION log type.
