Use auto value concept in summary plot configuration. Default behavior is unchanged, but it is now possible to unlink a field to specify a custom value for this field.
Other changes:
* Add missing requirement for Svg in test application
* Use calculator icon and rename panel text
Use icon and relevant text to make it clear that the content in Calculator Data can be used for Grid Property Calculator and nothing else.
* Add example with scoped enum and auto value
* Use enum value starting av 10 to make sure enum values (not option item index) are working as expected
