Sailing things right

Ok. I drew another dickpick on the map, calibrating autopilot in various configurations.

Turned out that since this computer never had a gyro-module installed it may not have the code to use it (firmware update required which I can't perform because of absence of the Raymarine chartplotter) hence disconnecting it returned the computer to the sane state and now autopilot successfully calibrated and somewhat doing it job.

Tho tacking function works a little funky: it starts tacking as intended, but starts recovering the rudder too early and can't finish the maneuver falling into the course error.

But, at least, I see it keeping course, does not skipping sectors at the compass, and follows the + and - buttons.

Already a huge success. Yay!.
