bbPress should implement HttpOnly Cookies to slow down XSS

Description

While it's far from perfect and there are complex ways around it, HttpOnly Cookies are supported now by all major browsers and will prevent many kinds of XSS attacks.

HttpOnly Cookies simply prevent cookies from being accessed via javascript's document.cookie so an admin's cookie cannot be easily forwarded to another domain via injected javascript.

The technique is this simple:

if (PHP_VERSION < 5.2) {
@setcookie( $name, $value, $expires, $path, $domain. '; HttpOnly' );
} else {
@setcookie( $name, $value, $expires, $path, $domain, NULL, TRUE );
}

I was waiting for one of these after Coding Horror featured it. :D It seems good, but I don't feel qualified to comment.

It's a wonderfully simple concept and is really a matter of just appending `.'; HttpOnly' to the cookie domain, regardless of official PHP support or not.

The problem is while all modern browsers support it (and doesn't break any old browsers) their support is imperfect and needs improvement. But that will be fixed over time and then users will have robust protection under WordPress/bbPress. Even with the current state of affairs it does add some extra security.
