extra commas throw errors in IE7

Lines 42 and 61 in popup-filter.js have an extra comma in them that caused errors on my IE. Removing the commas removed the error, and everything else appears to still work.

Should be:

body.animate({
        height: 'show',
        opacity: 'show'
      }, 'medium');

And:

body.animate({
        height: 'hide',
        opacity: 'hide'
      }, 'medium');
