Optional refreshment of totals in workbenches

Calculating totals can reduce performance. For this reason, you can now deactivate the automatic calculation of totals.

To support this, the Calculate Totals command has been added to various workbenches across LN. By default, this command is unmarked. You can mark it if totals should be retrieved automatically.

The setting of the command is saved for the next time you start the workbench.
