    SemanticProperties for Projections

    This PR deals with
    https://issues.apache.org/jira/browse/FLINK-932
   
    ProjectionJoins, Crosses and the regular project operator get their SemanticProperties generated automatically. Additionally, I disables withConstantSet() for ProjectJoins and Crosses because it can cause conflicts.
