[REL] Trevally - Harbour Pilot Scripts

[Trevally.]

Just finished the first test on non-precision.
It was bremen harbour.
Tested before patch 3 and work well.
Tested after adding non-procesion and noticed the following:-

Heading over short distance worked well.
Reduce heading checks worked well.
Response to next heading caused boat to overshoot. (basically the boat had to perform a u turn. The boat ended in the correct direction, but the u was wider than it should have been.)

All that showed me is that I should have used precision for the narrow areas of the harbour. (I should have done this anyway)
I did end the u turn at the correct heading.

I need to do more tests using precision and non-precision in the right conditions.
