Delete (Recreate Database) - WebWorker #617

Sorry if this is an obvious answer, I scanned through the docs, I couldn't see anything obvious where using the web worker I could delete and recreate the db file. There's obviously some cases where migrations go wrong, and would need to nuke the db. (Rather than telling users to go and clear the website cache :)
