Added this function to let you do slightly more complicated searches.

2001-06-11  Christopher James Lahey  <clahey@ximian.com>

	* backend/ebook/e-card-compare.c, backend/ebook/e-card-compare.h
	(e_card_locate_match_full): Added this function to let you do
	slightly more complicated searches.

	* gui/merging/e-card-merging.c (e_card_merging_book_add_card): Use
	e_card_locate_match_full to check if the card exists in the book
	it's being added to instead of in the default book.
