Call camel_folder_delete() on the folder if it's "alive".

2001-10-03  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-store.c (camel_store_delete_folder): Call
	camel_folder_delete() on the folder if it's "alive".

	* camel-folder.c (camel_folder_delete): Mark the folder as
	deleted, perform any folder specific cleanup and emit the deleted
	event.
	(camel_folder_sync): Only sync the folder if it hasn't been
	deleted.
	(camel_folder_expunge): Same.
