Enum property values should not be returned as QVariant objects

When accessed from QML, the Component "status" property is returned as a QVariant and not a plain number value.

Example:

 
 import Qt 4.7

 Rectangle {

     Component {
         id: aa
         Item {}
     }

     Component.onCompleted: {
         print(aa.status)
     }
 }

This outputs "QVariant(QDeclarativeComponent::Status)" instead of "1".

This can be fixed by changing QDeclarativeObjectScriptClass::property() to handle enum values.
