2003-12-03  Chris Toshok  <toshok@ximian.com>

	* lib/Makefile.am (libessmime_la_SOURCES): add e-asn1-object.[ch]

	* gui/smime-ui.glade: rename the ca trust dialog, and give it a
	proper id.

	* gui/certificate-manager.c (yourcerts_selection_changed): just
	use @selection.
	(contactcerts_selection_changed): same.
	(authoritycerts_selection_changed): same.

	* gui/certificate-viewer.c (free_data): free the cert chain.
	(fill_in_general): move all the general tab stuff here.
	(hierarchy_selection_changed): new function.  not finished.
	(fields_selection_changed): new function, unimplemented.
	(fill_in_details): new function, fill in the heirarchy and hook up
	signals and stuff.
	(certificate_viewer_show): call fill_in_general/fill_in_details.

	* lib/e-cert.c (e_cert_get_chain): new function.

	* lib/e-cert.h: add prototype for e_cert_get_chain.
