Feature to undo a delete - "recycle bin" style

[KZzizzle]

Create a "folder" for deleted studies during the last 30 days so that they can be retrieved if the deletion was a mistake.

can be done in "parallel" to the warning next to deleting a study #467

This has come up as well from Team Black on today's meeting (19.10). And will help also other users who might delete a study by mistake. How difficult is to implement @pcrespov?

@elisabettai We already did some trials with ideas. IMO it is feasible to have a first version within a sprint.
