Clone the current rule before editing it so that changes can be undone.

2001-09-12  Jeffrey Stedfast  <fejj@ximian.com>

	* rule-editor.c (rule_edit): Clone the current rule before editing
	it so that changes can be undone.
	(edit_editor_clicked): If the user hit OK, replace the original
	rule with the new one.

	* vfolder-rule.c (vfolder_rule_finalise): Free the sources list.
	(rule_copy): Implemented.

	* filter-filter.c (rule_copy): Implemented.

	* filter-rule.c (filter_rule_copy): New convenience function to
	copy one rule "into" another.
	(rule_copy): Default implementation.
	(filter_rule_clone): Use filter_rule_copy() internally to get rid
	of the nastiness/slowness of xml encoding and then decoding.
