#include "Cube.h"
Point*D Vector* subclasses for homogeneous coordinates. Vector4 doesn't set W component to one by default anymore, this is now handled by Point*D itself. This finally allows creating of 2D primitives and 2D position vectors without messing explicitly with Z = 1. All classes which should use Point instead of Vector were updated to use Point instead.

#include "Math/Point3D.h"
Primitives: Cube can be now solid or wireframe.

#include "Trade/MeshData3D.h"
Reduced #includes in headers. Magnum.h now doesn't include anything except OpenGL headers, thus changes in Math library don't trigger recompilation of everything, but only of things really depending on it. Math constants moved to separate file for similar reasons, de-inlined some functions to remove the need for some #includes.
