* Fixed some typos in the variables used to generate the session ids.
* The fakesessid_{user_login} transients are now storing arrays of session ids. This allowed for multiple (but limited) sessions per user if wanted.
* Added wp_bouncer_ignore_admins filter, if returning false even admins will be bounced.
* Added wp_bouncer_redirect_url filter, which can be used to change the URL redirected to after being bounced.
* Added wp_bouncer_number_simultaneous_logins filter, which can be set to limit logins to a number other than 1. 0 means unlimited logins.
* Added wp_bouncer_login_flag in case you want to hook in and do something right before bouncing (or potentially stop the bouncing).
