Allow to query for items by status
For the curation dashboard /process, we need to be able to query also for drafts and suggested versions of items.
Specifically:
- The contributor needs to be able to list her draft items
- The contributor needs to be able to list her suggested items
- The moderator needs to be able to see all suggested items
Ideally, this should be combinable with other filters, so it should be maybe integrated into the existing search methods?
