2-way SMS improvement

Previous state

When SMS replies were received and processed against an absence, the absence update was recorded against the single absence slip.

This meant that users would need to manually change the absence event type to an All Day absence in order for subsequent absence slips created to be superseded by the original absence.

New State

The addition of AbsenceEventType to the luAbsenceNotificationReply lookup table now allows for both the absence type code (and/or absence reason code) and the absence event type to be modified when a SMS response is received and processed.

The caveat being that if an absence type can only be changed from slips (luAbsenceEventType SynergyMeaning = Slips), to an absence with a SynergyMeaning of anything else, once.
