This commit adds a one-time password system. Users can generate passwords by using the `genotp` command (or manually queuing a set_otp event with the SHA-256 hash of the one-time password they want to set) and these passwords will be valid, along with the normal password, either until the computer shuts down (or the net daemon is killed), a new one-time password is generated, or the one-time password is used.
