* camel-sasl.c (camel_sasl_authtype_list): add an argument to say
	whether or not you want "PLAIN" in the list (so you don't end up
	with "Password" twice in the config dialog).

	* providers/imap/camel-imap-provider.c (camel_provider_module_init):
	* providers/imap/camel-imap-store.c (query_auth_types): We don't
	want PLAIN.

	* providers/smtp/camel-smtp-provider.c (camel_provider_module_init):
	* providers/smtp/camel-smtp-transport.c (query_auth_types): But we
	do.
