Describe the bug

There is a flag present in simulation launch conditions that either restricts lanch rod direction to directly upwind or downwind, or allows the user to specify a launch rod direction. When the .ork file is saved, this flag is not saved with it. When the .ork file is next opened, the flag value in the Preferences is used instead of the value in the simulation.

To Reproduce

1. Create a simulation. Make sure the "Always launch directly up-wind or down-wind" box is not checked. Save the simulation.
2. Looking at the saved .ork file with a text editor, observe that there is no element in the simulation for this flag.
3. Set the flag in the program preferences
4. Read the .ork file.
5. Observe that the flag is now set iin the simulation launch conditions.
