TDMService event listening system

[yous11aly]

For example, we would like to be able to listen to the TDBM "save" event witch is one of its method and trigger a log afterwards.
On Doctrime ORM you can listen to the "prePersist" or "postRemove" event and trigger an action once these events happen.
But actually when we are using TDBM to persist in the DataBase we don't have theses functionalities.
