Feature request: Password History

[stefnotch]

Various other password managers such as LastPass have a "password history". This stores the previously used passwords and allows you to see them, in case you need them.
This is pretty convenient in a number of cases, one of which is when changing your password on a website failed for whatever reason and you end up needing the previous password.

I want to add to this that generated passwords should also be logged whether they are saved or not. It did happen to me where I used a Firefox generated password to change my bank password only to find out that the generated password was never saved.
