Browsers and Cross Origin Headers

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run `davserver -D /tmp -n -J`
2. Create an empty file in `/tmp/hello`
3. Open a web page on `localhost:8000` for instance
4. Do an simple ajax GET request to `http://localhost:8008/hello`

What is the expected output? What do you see instead?

The GET response was expected with status code 200.
Got status code 0 with: "Cross-Origin Request Blocked: The Same Origin Policy 
disallows reading the remote resource at http://localhost:8008/. This can be 
fixed by moving the resource to the same domain or enabling CORS." (on Firefox)

What version of the product are you using? On what operating system?

PyWebDav 0.9.8, Firefox 29.0.1, Arch Linux

Please provide any additional information below.

Why not to add a `-a 'My-Custom-Header: Hello'` option to let user to add their 
own specific access control headers. Or something like `--cors`.
