Spelling error in a variable: $mobule_files

I was poking around at the release candidate code and noticed what looks like a spelling error in a variable.

<?php
foreach ($modules as $module) {
  $mobule_files = array();
?>

While this might be intentional, if it's not, here's a patch. Oh, and a link to a funny graphic that my co-workers dropped on my while I was rolling this patch: http://www.bimmerfest.com/forums/attachment.php?attachmentid=142024&stc=...

(FYI, this spelling does not occur in HEAD, so it's only intended for the 4.1 RC)
