The commit is slightly more complicated that expected because:
- it adds supports for both schuko and type-E, using the same icon (but
maintaining the underlying type annotated in OSM)
- it adds logic to *not* display the power of schuko socket as 'unknown'
when not provided in OSM, as it is 'implicit' (3.7kW in most
countries)

While here, uncluttered a little the charging station editor,
removing fields like the POI address which is basically irrelevant for
charging stations.
