Documentation on the website

[seregamuravyov]

There's nothing at http://www.cam.cornell.edu/~sc932/ALE/doc/index.html. And that's a pity.

[sc932]

The documentation has now been moved to:

http://sc932.github.io/ALE/ALE_doc/index.html

One can also build the documentation by running $make html from the doc/ directory (required sphinx).

Thanks!
