Cmake integration & project structure

[SirzechsLucifer666]

I'd like to update the project by integrating CMake and reorganizing the files as mentioned in issue #59. Because the code is still tightly coupled, we can't do this all at once. So, I suggest starting by creating the new file structure, putting all files in the core submodule. Then, we can gradually move the independent classes into their correct modules.
