Sarah Hoffmann 4bb56d98a8 simplify geometry handling in details page
Hand the WKT directly to OpenLayers and let the client do the parsing,
it will be able to handle multipolygons as well as line strings.
Simplify geometries if they have too many points.

Also limit the number of child objects listed to 500.
