Started implementing mh store/folder as a test provider. Next will be pop3.

1999-08-03  bertrand  <Bertrand.Guiheneuf@aful.org>

	* camel/providers/MH/camel-mh-folder.c (_create):
	implemented.
	(_delete): started implementation.

	* camel/camel-folder.c (_get_folder): default implementation
	calls camel_store_get_folder ().

	* camel/providers/MH/camel-mh-folder.c (_init_with_store):
	implemented.

	* camel/camel-folder.h (struct _CamelFolder):
	remove useless exist_on_store field.

	* camel/camel-folder.c (_exists):
	do not use exist_on_store field.
