	in imap_[g,s]et_message_user_flag() methods

	* 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.
