Implement Trajectory Manager

[Birdasaur]

• Implement trajectory tracking logic similar to how Distances are managed.
• Add trajectory list manager UI similar to Distances UI
• Each new file that is added to the view will automatically create a new Trajectory in the tracker.
• New trajectories will use the filename as the Trajectory Label by default
• Selecting a trajectory in manager will fire a new Active Trajectory event
• Trajectories Color and Visibility can be modified from tracker
• Hyperspace view will be updated to plot trajectories as static 3D polylines
• Projections view will be updated to plot trajectories as static 3D polylines
