Rows in spread tables appear out of order

When a table has lots of columns and may be sorted by any combination of them, it's helpful to display the spread in a consistent order.

This can be accomplished by changing lines 257-260 of views_summarize.module from

  foreach ($hist as $value => $count) {
    $rows[] = array($value, $count);
  }
  

to

  foreach ($hist as $value => $count) {
    $rows[$value] = array($value, $count);
  }
  ksort($rows);

Sorry, I suck at rolling patches, but perhaps someone who finds this useful will roll a patch. Thank you for a great module!!
