Currently saving the Tour results in a crash. Also the handling of the gx:duration property doesn't get taken into account right after creation of the tour. gx: duration is the time it takes to perform an animation between two locations.

So as part of the task:

- Change the default wait duration to "1 seconds".

- Ensure that the wait time entry in the UI (as gx:duration) is taken into account right after creation.

- Make sure the wait time (as gx:duration) is saved and loaded properly.

- Fix the crash when saving the tour.
