The trash management in PlatformUI is missing 15.12 missing feature. This EPIC is about producing this feature as specified in https://doc.ez.no/display/PR/Deleting+Content (It's already possible to send a Content item to the Trash).

Minimal viable scope is EZP-25206, EZP-25248, EZP-25249. The other 3 are nice-to-have, but not as important.
