	Policy change: NULL url's are no longer allowed in CamelFolderInfos. They used
	to signify that the folder was, in IMAP jargon, NoSelect; now the same effect
	is achieved by adding a "noselect=yes" parameter to the end of the URL. As far
	as I know, IMAP is the only affected provider.

	* providers/imap/camel-imap-store.c (delete_folder): New function. Implement
	folder deletion.
	(camel_imap_store_class_init): Set the delete_folder class function here.
	(get_folder_status): New function. Utility wrapper around the STATUS command.
	(create_folder): If the parent folder is NoSelect but is empty, delete it
	and recreate it as a a subfolder-containing folder. If it is NoSelect but
	contains messages, set an exception.
	(parse_list_response_as_folder_info): Always set the FolderInfo's URL, but
	add a NoSelect parameter if it isn't selectable.
	(get_folder_info_online): Change logic of removing the namespace to reflect
	URL change. Same for logic of checking unread counts.
	(get_folder_info_online): Use get_folder_status to simplify this.

	* camel-store.c (camel_folder_info_build): When creating
	dummy parents, copy the child's URL and set the NoSelect
	parameter.

	Track the NoSelect changes in Camel.

	* mail-callbacks.c (create_folders): We don't need to check if
	the URL is NULL or not anymore.

	* component-factory.c (create_noselect_control): New
	function. Create a dummy control for folders that can't contain
	messages (ie \NoSelect)
	(create_view): If the URI says the folder is noselect, make a
	dummy control. FIXME: still should merge in the global UI
	elements.
	(xfer_folder): Don't allow the operation if the destination is
	NoSelect.
	(destination_folder_handle_motion): Ditto.
	(destination_folder_handle_drop): Ditto.
