Reviewed by Sam Weinig.

Changed <select> pop-up menus on Mac OS X Snow Leopard and later to have their items aligned in the
direction corresponding to the writing direction of the <select> element, with the checkmarks
on the "start" side, and use the <option>'s writing direction rather than "natural". Made the
pop-up button match the menu by adding a Chrome boolean function, selectItemAlignmentFollowsMenuWritingDirection(),
which returns true for this pop-up behavior.
