P0-MS3: Part 233: AI, Debugging, etc

Continuing on with the debugging and final improvements, I have tested almost all of the gameplay features, and the vast majority of them had no issues.

I did run into some lighting problems and minor bugs, which were fixed.

I have also made improvements to the 3D radar system. These changes turned out to be quite complex, since I was adding objects that were placed a realistic distances from the ship. Due to floating point precision issues, I had to eventually create dummy objects with scaled down position values, and then plot these using the radar system.

I have also tested the voice recognition system, and purchased a professional voice from Cereproc, which is also working well.
