Added scoring xml stuffs

2000-09-08  Jeffrey Stedfast  <fejj@helixcode.com>

	* filtertypes.xml: Added scoring xml stuffs

	* Makefile.am: added filter-score.[c,h]

	* filter-score.[c,h]: New functions to handle the "score" filter
	type.

	* filter-element.c (filter_element_new_type_name): Added support
	for "score" type.

	* filter-driver.c (do_score): New ESExp callback for filter
	actions to set the score on a message.

	* filter-message-search.c (get_score): New ESExp callback for
	getting the score tag as an integer value.
