Added ability to save raw SQL script to server

Hi ClearMedia!

Thanks very much for opensourcing your backup tool. It was really useful in my application.
I made this one adjustment to it because I wanted to be able to easily restore the database, and saving the script to server works for us. It's only a tiny change, but if you think it might be helpful to someone else, please pull it. I won't be offended if you don't. :)
