Made it a little more forgiving. Also set current_folder to NULL as there

2000-07-23  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (imap_disconnect): Made it a
	little more forgiving. Also set current_folder to NULL as there is
	no selected folder after a disconnect.
	(stream_is_alive): Detects whether or not a socket is "alive"
	(camel_imap_command_extended): Use stream_is_alive() to aid in the
	detection of a disconnected state.
