ITI-31: Update to ZBE segment definition via CP by IHE-France

In ITI TF-2b to be published in July 2018, Final Text CP-ITI-749 will be integrated.

This CP updates the definition of the ZBE segment in Vol 2b. It also update the IHE-France National Extension in Volume 4 for this segment.

The CP is attached to this issue. I am submitting this jira report in case the PatientManager must be updated due to this CP.

Note: Message profiles shall be updated first in order to be able to regenerate the Java class based on the structure definition.
