Convert the "group" property on radio widgets to a GtkRadioGroupradio-group

The various radio widgets all have a write-only "group" property
of the same type as the widget. This let you set the group in a
bindable way, but is quite weird when we have a real GtkRadioGroup
object.

We convert this to a real read-write GtkRadioGroup type. Additionally
we make it CONSTRUCT and use it in the various constructors instead
of hand-rolling the set_group call.
