If the preferred authmech isn't found, default to the first one in the

2001-01-13  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-account-editor.c (source_auth_init): If the preferred
	authmech isn't found, default to the first one in the list.
	(transport_construct_authmenu): This function already did the
	above but I made it simpler.
	(apply_changes): A number of cleanups.
