WIP: Updating code to follow laupentin's code review.
Done: - Moved custom map structures to their own objcommon header file - Updated GfxLightGridRow struct - Reverted shader_bin file path - Renamed Project Creator to BSP Creator - Removed model loading from BSP creator - Cleaned up BSP Creator and updated the names of structs WIP: - Update BSP calculation code to be more readable and use unique/shared ptrs
