Cannot rename Apps that were created on the CLI

[matheus23]

Problem

I used the rename feature to rename an app created at the CLI last night, and it was failing. I realized looking at the error that it needed to be uploaded to WNFS. I wonder if it would be a good idea to give a help message in Dashboard to let the user know about that.

Impact

It's at the very least confusing to users.

Solution

It's a little tricky. To rename apps, we destroy the app and re-upload the 'same' app (as a CID) to another subdomain. But we don't know what CID to upload, unless the app's files are in WNFS.

Maybe we add a CID value to the apps.index()?
Maybe we add apps.rename()?

If #8 were implemented, this issue would be resolved.
However, that'd mean we'd need WNFS features in the CLI (which means we'd need a ... haskell webnative implementation?).
