If a regex option is selected, change the FilterElement data to TRUE else

2000-10-30  Jeffrey Stedfast  <fejj@helixcode.com>

	* filter-option.c (option_activate): If a regex option is
	selected, change the FilterElement data to TRUE else set to FALSE.

	* filter-rule.c (more_parts): Validate the previously entered
	FilterPart before allowing the user to add a new FilterPart.

	* filter-part.c (filter_part_validate): New convenience function
	to validate an entire FilterPart expression.

	* filter-input.c (validate): Validate the entry text if it
	contains a regular expression.

	* filter-element.[c,h]: New virtual function to validate the
	contents of the FilterElement (useful for regex and sexp).
	(filter_element_validate): You get the idea...
