Spiritus Astrum [P0-B11]: p1501: Towards Early Access

I have been working on improving the space combat mechanics in the project. I have made several minor changes to AI pathfinding and tweaked some variables to accomplish this, with good results.

I have also added mission triggers and logic for another mission to the game. I have not added artwork for this yet, just the core logic. There is still quite a lot to do for the third campaign, but I am making good progress.

In addition, I have added improvements to the way that dialog messages are presented to the player in the game (Particularly when they are in a vehicle) and I have also improved the NPC dialog system to add better integration for story-based dialog options.

There are probably more improvements that I will need to make here, but I think the system that I have works well enough for the time being.
