Added Version history to Password Vault. Each time an item is saved, on the website, in the app or in the browser extension, Magpie keeps an encrypted copy of the version it replaces. The item's page lists earlier versions with when each was saved and what changed after it. View shows an earlier version's values and Restore puts the item back to it; the version you replace is kept too.
Earlier versions are kept for at least 30 days, then the 10 most recent of each item. An item that cannot be decrypted is now listed on the Password Vault page instead of being hidden, so an earlier version of it can be restored.
