implement using the e-cert-trust foo. (e_cert_get_email): implement.

2003-11-12  Chris Toshok  <toshok@ximian.com>

	* lib/e-cert.c (e_cert_get_cert_type): implement using the
	e-cert-trust foo.
	(e_cert_get_email): implement.

	* lib/e-cert.h: add UNKNOWN cert type.

	* gui/smime-ui.glade: fix capitalization of "Import" on the
	contact certificate page.

	* gui/certificate-manager.c (import_contact): new function.
	implement email cert importing.
	(delete_contact): new function.
	(unload_certs): implement for E_CERT_CONTACT.
	(certificate_manager_config_control_new): get the contact cert
	action buttons from libglade.

	* lib/e-cert-db.c (handle_ca_cert_download): mostly implement the
	trust settings correctly.  this still needs work pending the CA
	trust dialog's completion.
	(e_cert_db_delete_cert): fix the ifdef'ed code.
	(e_cert_db_import_user_cert): remove the ifdef'ed body of this,
	since it was copied from the CA code.

	* lib/Makefile.am (libessmime_la_SOURCES): add e-cert-trust.[ch]

	* lib/e-cert-trust.[ch]: new files, basically c&p nsNSSCertTrust
	from mozilla's PSM.
