[Development] The future of QProperty and QBindable

We need to establish some "NOTIFY default" as part of Q_PROPERTYY that 
would produce a signal only on the metaobject level, but not as C++ 
declaration. Then you could search-replace all your BINDABLEs and add 
"READ default WRITE default NOTIFY default" to all of them. This, in 
turn would enable QML to use the property without the bindable.

I'll keep this in mind.
