Unhidding all select boxes on close, even those originally hidden.

In end function, lightbox allways shows all select boxes. It does not take care about the selects that must left hidden because ther originally were hidden.

$("select, object, embed").css({zIndex: '10500'}).show();

For example: If you have a fivestar widget (who uses a hidden select), when you close lightbox2, it unhide the select.
