Extension

Finally got my first extension working.

It was pretty easy all things considered. I had spent time trying to figure out what my end product should be but I didn't get started at the beginning until now. So far it doesn't do anything but I'm happy that I made all the files and everything works. Mozilla's tutorial is helpful for getting a hello world extension working but it doesn't really go past that.

Now I just need to get it worthy of a 0.1 release.
