Listings with short outputs cause time slider to fail

[Angus Yeh]

If listings has (AUT2) short outputs, the time/step slider will fail as it moves to a different step.

This is because module ui_control_time.py uses .num_times instead of .num_fulltimes as new index.

Fix issue #69 about time/step slider fail when AUT2 listing contains short outputs.
