folder names rather than constantly prepending it and stripping it
	off. Also some subscription fixes.

	* camel-store.c (camel_folder_info_build): Fix for the case where
	@top isn't in @folders.

	* providers/imap/camel-imap-folder.c (camel_imap_folder_new): Add
	a "short_name" argument rather than figuring it out ourselves.
	(imap_get_full_name): Implementation of CamelFolder::get_full_name
	that strips off namespace so the user doesn't have to see it.
	(imap_append_message, imap_copy_message_to, imap_move_message_to):
	Use folder->full_name rather than calling
	camel_imap_store_get_folder_path.

	* providers/imap/camel-imap-utils.c (imap_parse_list_response):
	Update this: make @flags a bitmask and @sep a char rather than a
	string. Make all of the out arguments optional. Handle literals in
	the server response.

	* providers/imap/camel-imap-store.c (imap_connect): Do a better
	job of getting the correct dir_sep for the namespace we're using.
	Construct a base_url here that will be used by get_folder_info.
	(camel_imap_store_folder_path): Removed
	(imap_folder_exists): Add an argument to return the short name of
	the folder (parsed out of the LIST response). Update for
	imap_parse_list_response change.
	(get_folder): Update for the various other changes.
	(get_folder_info): Update for the various other changes. Be more
	consistent about the returned layout: put everything underneath
	the "namespace" directory, including INBOX, even if it doesn't
	belong there. Don't destroy the list of subscribed folders until
	we've actually gotten the new list.
	(folder_subscribed, subscribe_folder, unsubscribe_folder): Use
	folder_name directly rather than camel_imap_store_folder_Path.

	* providers/imap/camel-imap-command.c (camel_imap_command): Update
	for folder name changes.
