Questions on testing and exporting

[Narroo]

I think I may have made a good change to some of the code, yay!

One problem; I'm having trouble figuring out how to test it. I fixed: "unload" console command should use cWorld:QueueUnloadUnusedChunks() #385.

Now, I'm not sure how to test it. I'm still not even close to understanding how the code fits together, and I'm new to projects like this, so I'm not sure how I should go about figuring out how to test it.

Then, once I do test it: How do I properly export this back to the cmake file so I can do a pull-request?

Thanks!
