Return the option as --digest-algo=<micalg> (gpg_ctx_parse_status): Decode

2002-06-25  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-gpg-context.c (gpg_hash_str): Return the option as
	--digest-algo=<micalg>
	(gpg_ctx_parse_status): Decode more status information and keep
	track of trust and such.
	(gpg_ctx_op_complete): Make sure we aren't waiting for gpg to
	write data to stdout (such as encrypted/decrypted data or a
	signature).
	(gpg_encrypt): Remove the fejj@stampede.org hard-coded value
	(which had only meant to be for testing).
