Only send the LOGOUT command if the store is connected. (imap_connect):

2000-10-16  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (imap_disconnect): Only send
	the LOGOUT command if the store is connected.
	(imap_connect): Set the 'connected' state to TRUE when we
	successfully connect.
	(get_folder_info): if (!topfi), 'topfi' was allocated but then
	'fi' was set. I think Dan meant to set topfi since fi is an
	uninitialized value at this point.

	* providers/imap/camel-imap-command.c (imap_read_response): Check
	for the untagged BYE response and set the 'connected' state to
	FALSE if we receive the BYE response. Return NULL if we get a BYE
	response.
