Fixed #2 - use finer-grained delta-t values without discontinuities.
Using historic, recent, and predicted values of TT-UT instead of UTC leap seconds. With linear interpolation, there are no longer discrete jumps in the calculated TT values. Hopefully, this will make event solvers (rise, set, etc) more well-behaved.
