Improve form deletion process.

• Deletion should only hide a survey from the UI.
• This will allow submissions for this survey to continue if a phone still the XForm on it.
• This will prevent the user from creating another survey with this ID. This is actually a good thing so that old versions don’t get mixed in with a newer version with the same ID.

Hey Andrew, I have a comment on this, and I think we have to work on this a little more. Basically, I see the issue that you raised above, which makes this tricky. But right now, we aren't letting people iterate on surveys in a good way. In a real life use case, you'll need to go through a survey many times before its perfect (and even then...).

So can I propose the idea of a sandbox, where deletion works differently, in that forms can de deleted forever, and the data alongside with it?

Then, we have another set that is not sandboxed, and which we assume are in deployed in "real life".
Actually, the way I am thinking is that this second set would be either in a state of "deployment" or "archival." Deployed surveys can be archived, but can never be deleted, for the reason you mentioned above. (Plus, there is data associated with it!) Archived surveys just sit there, and can be brought back into deployment, but again, can never be deleted.

whatcha think?

Okay, I'm going to make a new issue based on this idea of a sandbox, because needing to iterate on forms is a crucial thing that formhub should allow IMO. We can discuss on that issue how best to do it though.
