Fix broken value-type support by allowing property definition

In QtQuick 1.x the "variant" property type was supported, which could
be used to allow value type properties to be defined in QML.  In
QtQuick 2.0, we have deprecated the "variant" property, but its
replacement ("var") is not suited for defining lightweight C++ type
values (such as QColor, QFont, QRectF, QVector3D etc).

This commit allows those QML basic types to be used in QML once more,
by supporting them in the property definition syntax.

Note that since some value types are provided by QtQuick and others
are provided by QtQml, if a client imports only QtQml they can define
but not use properties of certain types (eg, font).
