I'm strongly opposed to autogeneration of getters and setters, because this is
far from being "standard case", except the most trivial situations, however it
would be great if it was possible to avoid duplication of property name inside
Q_PROPERTY for getter, setter and signal, and instead use naming convention
(property, setProperty, propertyChanged)
