use folder summary instead of opening all messages.

1999-09-05  bertrand  <Bertrand.Guiheneuf@aful.org>

	* tests/ui-tests/store_listing.c (show_folder_messages):
	use folder summary instead of opening all messages.

	* camel/providers/MH/camel-mh-folder.c (_create_summary):
	basic and highly non-efficient summary implementation.
	Should be seen as a proof of concept only.
	subfolder summary still has to be implemented.

	* camel/providers/maildir/camel-maildir-folder.c (_init_with_store):
	hasn't summary for the moment.
	* camel/providers/maildir/camel-maildir-folder.c
	cosmetic changes.
