Use event pass instead of native invoke between components

[alsor.zhou]

Currently (v1.0), most of the messaging mechanism was thru native
invoke, like
class FxSetting
{
FxMainWindow *m_mainwindow;
}
In this case, FxSetting will keep a mainwindow instance. It might cost
memories, and make code mysterious. If FxSetting really need that
mainwindow instance, it can be implemented thru signal/slot, which is
dynamically used and destroied.

Generally, different components should not contain other component
unless the sub component.

Hi alsor,
It just keep a point of mainwindow, so I think it will not cost
memory.

Thanks,
