Last section: show *used* and *unused* 'network' values

[osm-ToniE]

The last section in the output HTML should be split into two parts:

• "Berücksichtige 'network'-Werte" --> new, showing ???
• "Nicht berücksichtigte 'network'-Werte" -> exists, showing also their relations

Maybe add a "second" column showing how often the value/combination has been seen.
