add .not

use case:

$('li').not('.selected').doSomething();

adding this now, @visionmedia question: is it uncouth to use this.forEach to iterate the lists own elements? i notice it could have been used in a bunch of other methods, but instead you use a new for loop each time, why?

just to avoid a ton of function calls for big lists etc but not a huge deal either way
