Audit trail of masterfile changes

[Mike Palandri]

On the Alpha, we use OVMS mailbox files, which are sorta kinda like MPE
temporary files.  In each field edit procedure, the last step calls an
internal that writes the changed info to the mailbox file, in your case
this could include old and new values.  The update procedure writes the
contents of the mailbox to the a permanent audit file, if the user does
not update, the mailbox contents are discarded.
