 * Hi!
 * I’m trying to modify the behavior of the image edit tool and need to do a few
   changes to a JS in admin/js/ …
    is there a way to tell a plugin to dequeue a 
   core-script and call a custom script instead???
 * i don’t want to mess with the files again after every update…
 * thx in advance!

 * `wp_deregister_script` – sorry couldn’t find a codex page for it

 * Unregister the existing one, then register your own with the same name (that 
   way you won’t cause any enqueued scripts that have dependancies on that file 
   to fail).
