Great plugin but broken in PHP 5.4 – here's a quick fix

Great plugin, but is broken under PHP 5.4+ as the plugin attempts to pass a string in as an array (previous PHP versions were more forgiving and ignored the type error).

If you’re getting the “Warning: Illegal string offset ‘list_only’…” error, a quick and dirty fix is to manually edit the plugin and insert the following code line into summary-child-pages.php on line 56 (inside the summary_child_pages function, right before the $list_only = $atts['list_only']; line):

/* ---------------------------------------------------*/
  /* Version v1.0.0: Patch for error under PHP 5.4+ to   */
  /*  address the "Warning: Illegal string offset        */
  /* 'list_only'" issue. An array (not a string) is      */
  /* expected, so check & convert $atts string to array. */
  /* ----------------------------------------------------*/
  if (!is_array($atts)) {$atts=explode(',',$atts,0);}
  /* ----------------------------------------------------*/

This checks to see if $atts is not an array, and converts it to one if so. If anyone has a better solution feel free to post it ??

To the developer: Thanks for making such a useful little plugin, and if possible could you please fix this in the next update so it works properly with PHP 5.4+? Thanks!
