Update

- Scrapped the current rendering engine and started implementing the world in full OpenGL.
- Implemented more fancy engine and model classes.
- Finished with the rendering and movement parts.
- No screenshots yet because it's still very crude. Basically it's only 1 object in the view and world movement.

I'm working on the static world representation for now (positioning of meshes and static world geometry).
Maybe some screenshots when I'm done with that.

Early shot from the 0.1.6 version. Static world geometry with triangle representing the player.
Added model classes for structures, ground, player and camera.
