Made changes and fixed some issues

First of all, I wanted to thank you for this class helper. I know that the current version has a few issues but for the most part it was a great start for me. In this file you will see that I added the new WP 3.0 media uploader. Also, I fixed a few issues with the image uploader. I deleted a few fields that I personally will not be using in my projects but can easily be implemented into this file again if needed. You will probably need to add jQuery for the repeatable rows to work too. 

Thanks again for this!
