P0-B1: Part 1015: Debugging, Improvements

I have fixed some issues, and made some improvements, to the snow exclusion system. There were some minor problems here that I needed to fix.

I have also begun expanding the tests for the project. I am currently testing and improving the random planet generation system.

So far it is going well. I am making some improvements to the distribution of random objects and resources on the various planets.

I need to incorporate the terrain steepness of each planets, as well as the radius, and the random probabilities of each resource being created.
