Provide link from ingested dataset to the ingested CHOs

[kba]

When an ingestion using the Omnom Publish plugin is finished, Omnom provides a link to the ingested dataset in Pubby.

Example job page: http://omnom.hu-berlin.de/#job/http://omnom.hu-berlin.de/api/job/9e778460-51a4-4ef3-971d-01450714fbc3

Example pubby link: http://lelystad.informatik.uni-mannheim.de:3000/data/html/ingested/ONB/ONBCODICEStest011013/1381143806017

How can I browse the data in that dataset, maybe get statistics about them as well?

This is crucial for the providers (see DM2E/dm2e-gui#28)
