Planning UI should display stats from previous runs

[jelster]

If the player has ran the simulation during the current session, the game should display the stats (inc. the outcome) in a non-priority reference data part of the UI.

Minimum data to display:

• flight time
• Distance traveled
• Launch force
• Ending state (e.g., CargoDestroyed)

Implementation note: Probably will need to create a data structure to hold game stats - also needed for scoring
