Add a couple type checks in gtk_activatable_do_set_related_action() to
allow both GtkWidgets and GtkActions to implement GtkActivatable. Bug
602099 describes a use case for this.
Also add a GObject prerequisite to the GtkActivatable interface.
* gtk/gtk.symbols:
* gtk/gtkactivatable.[hc]: Rename gtk_activatable_reset to
gtk_activatable_sync_action_properties, since the previous name
was deemed too generic. Update all implementations.

Rework the way actions and proxies interact, to make the
interaction less ad hoc, more extensible, and better suited
for support in GUI builders like glade.
To be used as a proxy, a widget must now implement the
GtkActivatable interface, and GtkActivatable implementations
are responsible for syncing their appearance with the action
and for activating the action.
All the widgets that are commonly used as proxies implement
GtkActivatable now.
