Bug and fix: Error in IE

When displayed in Internet Explorer, shows an error message on the bottom status bar.

Cause: filename sites/all/themes/ability/js/jquery.pngFix.js file is capitalised differently from the reference to it in file sites/all/themes/ability/template.php, which is js/jquery.pngfix.js.

Fix: rename the file to all-lower-case to agree with the name in template.php.
