[DATASTORAGE] Implementation SaveMode for flat file DS
Brought to you by:

Implementation SaveMode for flat file DataStorage:
- CSV
- JSON
- XML
- XLS/XLSX
Now we use this DS in readonly mode. But if we try save data we can destroy file structure.
For example we can lost some nodes/attributes in XML file.
Maybe we need use special config property: Owerwrite Structure
