1. Create a new SyncedCatalogComponent catalog called
   "_Manual_Additions". This holds manually added DSOs that were not
   resolved from the internet. The concept is however the same -- it
   is a fake catalog for such custom added objects.

2. Build a UI for the purpose of manually introducing objects into
   this catalog.
