Bad Behavior 2

I've been getting this issue and tracked it down to a couple of items.

Originally on the site, the eu cookie option was not enabled, so bb2_screener_cookie was setting a cookie with the expiration time of 0 (when browser session ends)

Later the eu cookie option was enabled, so now bb2_screener_cookie does not set a cookie (as expected), however Chrome (latest version as of 12/13) still sends back the cookie. Doing a search on when browser session ends, it seems chrome has its own ideas of what that means. So the result is Chrome will continue to send back the old cookie and that will trigger the b40c8ddc error.

Possible solutions are
1) don't use 0 as the expire time on the cookie (due to the way chrome handles it) but set a valid time limit, allow that to be set in $settings and if not set then default to 0. Then the cookie will expire naturally and Chrome will not send it

2) Before using the cookie in bb2_post, check the $settings['eu_cookie'] status to make sure you should be using it at all.
