Using 'include "[filename].moc"' fails

When a QObject class is declared in a cpp file with the Q_OBJECT macro, moc does not appear to be run on the file. The standard (though apparently poorly documented) way to make that happen has been to 'include "[filename].moc" ' at the bottom of the cpp file. That is not working with the 3.0.1 VS plugin.

Example project attached - this builds fine with Qt Creator, or the 2.10 plugin.
