title: opposite of _.where(list, properties)
body: <p>I have an array of objects and I set <code>Selected = true</code> to some customers.
  Using <code>_.where</code> I'm getting a new array which have only the selected customers.
  Is there any method to get the customers who don't have this attribute?
  I don't want to set <code>Selected = false</code> to the rest of the customers and grab them by</p>
  
  <pre><code>_.where(customers, {Selected: false}); 
  </code></pre>
  
  <p>Thank you very much!</p>
