Added the camera class

Added the DDS Texture Loading for future use
Added the gamepad class for future use
Added first child method to the scenegraph
Added RGB to intensity and lerp methods to the shared methods class
Added the terrain node class with normals
Fixed issue with submeshnode not passing the world transform to the actual meshes
