Fix for bug #48791 (and also fixes a FIXME)

2003-09-23  Jeffrey Stedfast  <fejj@ximian.com>

	Fix for bug #48791 (and also fixes a FIXME)

	* em-format.c (emf_init): Setup a gconf listener for changes to
	the charset setting.
	(gconf_charset_changed): Update the cached gconf charset value.
	(emf_finalise): Free the EMFormatPrivate data, unref the gconf
	client, disconnect the charset notify id, and free the cached
	gconf charset value.
	(em_format_format_text): Use the cached gconf charset value.
