Fix in Readme.txt for settings.php

For the section that must be added to the site's settings.php file, you might want to make it more apparent that the user might need to change the path in the following line:

$conf['session_inc'] = './sites/all/modules/no_anon/session-no-anon.inc';

If a user installs the module into, for example, sites/example.com/modules/, then he would need to change the path accordingly. If I were at my home computer I could make a patch with this documentation, but I can't from work.

It might also be nice to mention that it doesn't matter where this line goes in settings.php, or to say "add this line below such-and-such section in the settings.php file."

Thanks for wrapping this into a module, btw; I always hate hacking core! (I like kittens, don't like them being brutally murdered by core-hackers).
