[1.4.0]Fix for Upload products images with IE 7

I saw that with IE 7, upload of images not works neither in product nor in category (I'm using Opencart 1.4.0) because java throws an error. I found a solution to avoid this problem and I hope that can be useful.

At line 130 of upload\admin\view\template\common\filemanager.tpl there is this line:
You have only to remove the final comma and it works with Firefox, IE 7, IE 8.

Good job for this wonderful E-commerce!
Bye!
