[Snapshot Pro] Delete Cloud Storage Backups from HUB and/or Local Snapshots for Auto Updates

I LOVE the automatic updates feature added to WPMU, but the cloud backup filling up and breaking the updates is really frustrating.

1) At the very least, a central place in Hub we could delete ALL backups instead of having to sign into EACH WEBSITE to manually delete EACH BACKUP would be fantastic.

2) The better option would be to allow Snapshot Pro to do LOCAL backups instead of only allowing it to use the cloud ones.
