GPL copyright statements added to top of each source file

The script works...mostly.

One thing I didn't know about XML files is that the XML tag **has** to be the first line in the file. It's annoying, and it's something that didn't show up in my early tests. 

I fixed the XML files manually, but I haven't rewritten the script yet.

You, my friends, have a choice. Pull this in now, or wait until I rewrite the script, maybe tomorrow.
