creates an Evolution_ServiceRepository object.

2000-03-12  bertrand  <bertrand@helixcode.com>

	* shell/evolution-service-repository.c:
	(evolution_service_repository_new): creates an
	Evolution_ServiceRepository object.
	(create_evolution_service_repository):
	create the corresponding servant.
	(evolution_service_repository_construct): set
	the closure as well as the virtual functions.

Completed the implementation.
The bonobo components can now implement a
Evolution::ServiceRepository interface.
