Enhance config importer to clean up and reduce information.
Improve `fetchDeviceInformation` to try ports 80 and 3000.
Adapt value text search to new reduced data structure.

Previously that search for value texts on a type did not start at
the type included in the value itself, but at its base type. This
patch changes that behaviour since the reduced and cleaned up
data structure relocated all value texts into the value's type.
