title: remove actions defined with function(){...} wordpress
body: <p>Have you got an idea how to remove <em>actions</em> or <em>filters</em> in <strong>Wordpress</strong> (from a plugin in my case) when those are defined like so:</p>
  
  <p>add_action('action_tag', function(){...});
  or
  add_filter('filter_tag', function(){...});</p>
  
  <p>They are defined inside the function <em>add_action</em> or <em>add_filter</em> so I have no clue witch 'function_name' I should use to remove it.</p>
  
  <p>remove_action($tag, <strong><em>what am I supposed to put in here?</em></strong>, $priority); </p>
