P0-B6: Part 1330: Debugging, Improvements

I have made extensive improvements to the Capital ships in the game, and the actions and events that the player can take part in while they are on-board.

There is a more advanced damage control system now, where gravity and power can fail if certain systems are damaged, etc.

I have also added a visual effect when the players ship gets too close to a star, or enters the atmosphere of a planet.

In the future, I want to allow capital ships to land on planets, and I want to add more events and things to do on board the ship.
