Updates to ET navigation demo scene due to accomodate for updated scripts

- Needed to update parameters due to script changes
- While at it, update of description text re-enabled the eyes+hands rotation.
- Disabled sending back the summoned hologram when looking off of it, as this triggered sending it back, every time I raised my hand due to a focus switch.
