2003-09-12  Jeffrey Stedfast  <fejj@ximian.com>

	* providers/local/camel-mbox-folder.c
	(camel_mbox_folder_get_full_path): Implements
	CamelLocalFolder::get_full_path() (publicly namespaced so that
	CamelMboxStore can re-use them).
	(camel_mbox_folder_get_meta_path): Same.

	* providers/local/camel-mbox-store.c (get_folder): Changed the way
	the path is constructed, since we now handle subdirectories and
	stuff.
	(delete_folder): Try deleting the Folder.sbd directory. We also
	need to manage our own meta files since CamelLocalStore's impl
	constructs paths differently than what we need.
	(create_folder): Implemented.
	(rename_folder): Implemented.
	(scan_dir): Scan an mbox tree
	(get_folder_info): Implemented using scan_dir().

	* providers/local/camel-local-store.c (delete_folder): Set fi->url
	to the correct value, meaning we need to prefix it with the
	protocol and the folder_name is not actually part of the path, it
	is a separate component to the url.

	* providers/local/camel-local-folder.c
	(camel_local_folder_construct): Use the new class virtual method
	to construct the full folder path and all the meta files.
	(local_get_full_path): Implemented default get_full_path method.
	(local_get_meta_path): Implemented default get_meta_path method.
