Updated for changes to PGP code.

2001-04-12  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-accounts.c (pgp_path_changed): Updated for changes to PGP
	code.

	* component-factory.c (owner_set_cb): Don't init openpgp anymore
	because we don't need it.

	* mail-crypto.c: Simply wrap the camel-pgp-mime functions (also
	renamed the functions to be prefixed with mail_crypto).

	* mail-format.c (handle_multipart_signed): Update to use
	camel_pgp_mime_is_rfc2015_signed() and other camel-pgp-mime
	functions.
	(handle_multipart_encrypted): Same but for rfc2015_encrypted.
	(decode_pgp): Updated to use camel-pgp-context
	(try_inline_pgp): Updated to use camel-pgp-context's.
	(try_inline_pgp_sig): Same.
