[evolution] sfpegMassActionCmp - Support best effort DML operations instead of atomic ones

[pegros]

For now the sfpegMassActionSoqlDml_SVC service class only supports atomic DMLs.
It would be better to support "best effort" DMLs and feed back the operation result on the datatable via the _result property (including the error message for each row).

Implementation done on commit d6cd644

[pegros]

Upon action, a result object is returned for each input record and a status, icon, message... updated on the original row displayed in the datatable. Implementation of DML actions has been adapted accordingly, enabling to highlight which record were successfully processed. Best effort DMLs are proposed in addition to atomic transactions.
