Fixed merge conflicts
Commit-bomb. Moved all classes to futurerl namespace, fixed fov bugs, some dumb moments that vere done in code due to my young age and stupidity, also I've fixed some spelling/grammar mistaces in comments, added TODO and ROADMAP files to make my development more target-driven, than it is now. I've got some thoughts on what to do more, but they are still not implemented, so I'm fixing this intermediate result.
