WalletTool: allow rotation time to be specified in seconds.
Key rotation: fix bug that could cause multiple identical key chains to be created over and over if the key rotation time was equal to the time of the oldest best key, with test coverage.
Default risk analysis: fix an off-by-one error in dust output comparisons.
