title: How to change FancyBox 2 options on the fly?
body: <p>I have a FancyBox 2.1.5 and it's using overlay "closeClick: true", meaning that FancyBox will close when the overlay is clicked anywhere. I'm updating the FancyBox content dynamically in various ways and would like to be able to change the overlay closeClick behaviour to "false" in a certain scenario.</p>
  
  <p>Is there a way to update FancyBox options dynamically in this way? This change in behavior would not be relatable to any of the ready events/callbacks but would be user-initiated.</p>
