Need some way to specify the QML module an add-on qmlclass comes from

Qt/3D uses the "Qt.labs.threed" namespace/module for its QML items. There isn't currently a way in the qdoc syntax to specify this in the qmlclass description such that "This class is declared in version 1.0 of the Qt.labs.threed module" appears in the docs, or to indicate that "import Qt.labs.threed 1.0" is needed to use the item. Perhaps something like:

\qmlclass Rotation3D QGraphicsRotation3D
\qmlmodule Qt.labs.threed 1.0

or in one line:

\qmlclass Qt.labs.threed.Rotation3D QGraphicsRotation3D 1.0

The version number at least probably should be added to qdoc so that when new items are introduced in Qt 4.8, they can be properly tagged.
