Add Navigation board

[jaghaimo]

A new navigation board that allows to add manage and use a quick access list of locations.

Tab 1: Manage locations (add, remove, reorder?), take course, add to trip.

Tab 2: Current trip management, autopilot on/off. On autopilot will go to the first location, then switch to the next one until it arrives at the end. If location is a market, will dock before continuing.

Tab 3: Trip management: load, delete, save trip data.
