-Added "shoals" and boat draft depths - smaller craft will now be able to sail closer to shore without "grounding" themselves. This is represented visually by different color (shallower) water.

-Built out the "rumor" mechanic where players can purchase information on nearby ports trading good prices
-Built out goods price tracking - upon visiting a port and opening the trading post menu your crew will automatically document the prices of goods at the port at that time and save them to your map. You can update this information by returning to the port and opening the trading post again.
