change the way x-evolution-any-field is converted to an ldap query. it

2001-07-25  Chris Toshok  <toshok@ximian.com>

	* backend/pas/pas-backend-ldap.c (func_contains): change the way
	x-evolution-any-field is converted to an ldap query.  it used to
	be we'd nest queries like: (|(|(|(foo=*x*))(bar=*x*))(baz=*x*)).
	now we build it like: (|(foo=*x*)(bar=*x*)(baz=*x*)).  much more
	efficient (both in the building, and on the server side no doubt).
