[Fixed] over-engineered Getter-methods

- the methods would semi-automatic search and set/ save params
- I removed those and set it back to its base functionality:
-- saving happens ONLY at the save() function if triggered by the user in the admin-frontend
-- only one Getter who checks for a value in the DB ? give the value : no value given yet
