DATAJDBC-99 - Eventsupport.

The repository publishes events before and after inserting, updating and deleting entities, as well as after instantiation of entities.

JdbcEvent ist the common super class of all events and makes the id
and the entity available (if possible).

Added issue id comments to tests from previous issues.
