Latent optimizations

So I've been refactoring the project and changing most of the integers to long so I can generate larger maps is going well, there were some hiccups here and there but it's still an ongoing process.

I also noticed some potential optimizations in the chunk rendering part which I've now added, I noticed these because I changed the cube array in the chunk to the length of 4096 from 2048 to take advantage of the previous optimizations (which I mentioned here Rivers, streams and more optimizations), the change was a double edge sword as the chunk rendering took twice the amount of time to render a chunk, fortunately I noticed that there were some potential optimizations as it sped up the rendering from 5 to 11 times faster.

I've also reduced memory usage by hundreds of megabytes depending on how many chunks are possibly visible, I only removed index an int variable and a vector3 position from the cube class as they can be easily generated if needed, as I mentioned a chunk has 4096 cubes and over 8000 chunks can be visible, the amount of memory needed for position and index is massive.

One down, thousands to go

So I finished creating the GUI based on Samuli's concept art and I can now start working on the gameplay... not.

I found a memory leak in the terrain generation that's resulting either in garbage collector not clearing or it's something I've done, I'm guessing both, so I have to trace it which means refactoring the terrain generation, although this prevents me from continuing the gameplay, but good news is that I can modify the terrain so I can create the actual size I was planning.

I was also planning in adding the cube unwrap which I've talked for so long now, but it dawned on me that the normals in the mesh would suffer, rendering a cube properly would need all 20 verticies otherwise I would need to rotate the angle of the normals and I have no idea what that would look like...
