More work on datatypes theory combination: fix bug in care graph, do not assign values for EQC of datatype type that contain only terms belonging to other theories, do not treat APPLY_UF as congruence operator, communicate equalities involving terms of external kind. Minor fixes for fun_def_process. Other minor changes.
