Drop Q_GADGET from most uncopyable classes; other minor cleanup

Q_GADGET is generally used to enable two things outside of QObject:
Q_PROPERTY/Q_INVOKABLE and Q_ENUM/Q_FLAG. While the latter can be used
in its own right in QML, the former requires Q_GADGET instances to be
passed to QML by value, which is not really possible with
uncopyable/unassignable classes. Bottom line is that Q_PROPERTY in
anything derived from Quotient::Event is not viable, making Q_GADGET
macro useless unless there's a Q_ENUM/Q_FLAG (as is the case with
RoomMessageEvent, e.g.).
