Initial work on URL completion in nsgtk. Some problems still exist.

1. It works without the code that should be required to make it do so.  Boggle.
2. It appears to include the URLs to images and other resources as well as pages
3. Although you can highlight a completion with the cursor keys, pressing enter on one doesn't work - you need to click on it with the mouse.
