Update 6 - Stepwise introduction of the ObjectEditor

To enable a gradual introduction of the ObjectEditor (OE), object types whose attributes are to be displayed with the OE can now be marked in the sisNET configuration.

The line {0, 9, 1} is to be used for this purpose. Normally the line {0, 9, 0} only specifies the module for the graphics.

Additionally, the SISNET_USE_OBJECTEDITOR environment variable must be set to 2. If SISNET_USE_OBJECTEDITOR = 1, the OE is used for all object types.

Note: if relation objects are called from the respective tool (FORMS or OE), they will be displayed with the same tool, regardless of the configuration flag.
