Added in imap_[g,s]et_message_user_flag() methods (imap_get_message_info):

2000-07-18  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-folder.c (camel_imap_folder_class_init): Added
	in imap_[g,s]et_message_user_flag() methods
	(imap_get_message_info): Rewrote to use the more efficient way of
	downloading summary information and also added a UID comparison so that
	if the UID requested doesn't match the UID received, it returns NULL.
	FIXME: When the mailer gets NULL when it requested message info, it
	seems that it displays a row for that message and when you try and select
	the blank row, it segfaults.

	* providers/imap/camel-imap-store.c (get_folder): Oops, this should not be
	checking against "/", it should be checking against dir_sep.

	* providers/imap/camel-imap-folder.c (imap_parse_subfolder_line): Updated
	to trim out the leading namespace.
	(imap_get_subfolder_names): Let the subfolder parser trim the namespace
	off the folder name.
