Fixed the broken tube commands, updated to 1.61 for that. Thanks man!

There's just no way to do absolute headings. For two main reasons: 1. I have no way to know the current course of the ship, 2.) even if I assume it is North on game start with some kind of reset command, it would lose track quickly if you issued a second heading change while the boat is still turning to meet the first.
