Clarification Improvements

Clarified some details that came out of a demonstration with co-workers:

• Improved directions explanation in the info display.
• Added color-coded region outlines to the example map in the info display.
• Added treasure reward summary to results display, and reformatted how fuel bonus was communicated.

Bug Fix:

• Certain directional river hints were not displaying the origin of the hint as "River's Mouth" when they should have.
