More descriptive AttemptTooSoonError

I think a better AttemptTooSoonError would be

Account is currently locked. Try again in 135 seconds. You have 8 attempts remaining before account lockout.

It doesn't compromise security when you use it in conjunction with a prudent value for the maxAttempts variable.

      var AttemptTooSoonMessage = 'Account is currently locked.  Try again in '
        + Math.round(calculatedInterval / 1000) + ' seconds.  You have ' 
        + (options.maxAttempts - user.get(options.attemptsField))
        + ' attempts remaining before account lockout.';
