Removed legacy code

Removed the OWL info from this module, it has his own implementation in
islandora_solution_pack_ontologies
Modified Importer Code to handle large data

I was wrongly passing a very big array to batch. Now the data gets
serialised and written back to disk and only reloaded in the
preprocessor. It can handle (empirical) for now at least 4000 objects.
Still getting some notices after the data is processed:
ingest.batch.inc on line 415 ,islandora_batch_process_results().
removed some blank lines
added some missing fields in darwin core forms

Also added the same fields to the importer templates
