idl/Registry.idl : temporarily changed register_Application

	idl/Registry.idl : temporarily changed register_Application
	to oneway, to work around issue with initial registration
	re-entrancy.
	* idl/Application.idl : changed attribute "id" from readonly
	to read-write, since it needs to be assigned by Registry.
	* registryd/registryd.c : added call to set application id
	on registration.
	* registryd/registry.c : changed de-registration procedure to
	use CORBA_Object_hash() to find matching object ref in application
	lists and listener lists.
	* registryd/registry.c : defined EventTypeStruct and EventTypeMajor,
	began distinguishing between event types (work in progress).
HANGES:
	* libspi/application.c:
	Added implementations for get/set id, get_toolkitName,
	get_version.
	* registryd/registryd.c :
	* test/at.c :
	* test/app.c :
	* Makefile.am :
	Converted from use of OAF to bonobo-activation.
	* libspi/desktop.h :
	* libspi/desktop.c :
	* test/app.c :
	Removed references to atksimpleobject, since base atkobject
	implementation now provides functionality we need.
	* libspi/atksimpleobject.c :
	* libspi/atksimpleobject.h :
	Removed.

	ADDITIONS:
	* at-bridge
	* at-bridge/Makefile.am

	This code is a GTK_MODULE which automatically registers
	GTK+ apps with the accessibility registry, using an object
	reference to the root ATK object.
