GtkSharp/gtk/RadioMenuItem.cs
Bertrand Lorentz 6809865526 gtk: Make the Group property for Radio* widgets a properly typed array
The Group property for all the Radio* classes (RadioAction, RadioButton,
RadioMenuItem and RadioToolButton) was exposed as a GLib.SList,
with its elements untyped.

We now hide the various Group properties and have custom code to handle
them correctly.
