Integrating changes to OpenEMPI messages

@devcritter , apologies, this is long overdue. Are you referring to the need to log failing merge requests in a separate log table ? if so, unfortunately we cant do this right now - there's no log table designed for logging merge request transactions.
However, there is another problem. This change is required for certain OpenEMPI modifications that we made. I believe that Wayne wants this to be part of the next release to be implemented on RHIE.
Since it'll take quite some time to add logging tables for merges, would it be ok to accept this pull so that Wayne can use it ?
