Update whatsnew documentation with value-type improvements

Value types are now supported as property types.  QtQuick provides
several new value types.  Subproperty modification write-back
semantics have been fixed for variant properties.

+Support for various math and geometry-related value types, including QVector2D, QVector3D, QVector4D,
+QMatrix4x4 and QQuaternion, as well as QColor and QFont, are now provided by QtQuick.  Properties of
+these types can be declared in QML documents via the property syntax where the type name is \c vector2d,
+\c vector3d, \c vector4d, \c matrix4x4, \c quaternion, \c color and \c font respectively.

+QtQuick also provides implementation for the various value type factory or utility functions of the
+\c Qt object which return or operate on values of the above types.  The functions are:
