Add Stopwatch.start_stop_seconds(), don't use timedelta.total_seconds().

This function is only available in Python >= 2.7. On

  http://docs.python.org/library/datetime.html#timedelta-objects

it says total_seconds() is equal to

  (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6

with true division enabled. We are using

  td.days * 24 * 3600 +
  td.seconds +
  operator.truediv(td.microseconds, 10**6)

now in Stopwatch.start_stop_seconds(), which I find more readable.
