starting to merge vulkan with the engine

- refactored scene_main to be able to share code between software and
  hardware renderers, while still sharing code between terminal software
  renderer and graphical software renderer
- made the hardware renderer use scene objects vertices and transforms,
  instead of hardcoded ones
- made the hardware renderer use the scene's camera
- made .obj parser create Vector3 instead of Vector4, which didn't made
  sense
- removed unnecessary std::
- lots of small changes
