Persist/reload Test Scenario table width/height

Implement a mechanism to store/restore column width (FactMapping) and row height (Scenario) for the table in Test Scenario.
Please consider:

• Create/save a simulation (default column width/row height in scesim)
• Rename a simulation (it perform a save/reload)
• Change column type (recreate the column)
• Duplicate column (preserve same size)
• Duplicate row (preserve same size)
