* This function lets you log a client or administrator in programmatically. By default, it logs the user in

* all. If you choose the latter, make sure you've initiated SESSIONS on the calling page - otherwise the
* login account information (needed to be stored in sessions) is lost.
*
* @param array $info a hash with the following possible parameters:
* "username" - the username
* "password" - the password
* "auto_redirect_after_login" - (boolean, defaulted to false) determines whether or not the user should
* be automatically redirected to a URL after a successful login.
* "login_url" - the URL to redirect to (if desired). If this isn't set, but auto_redirect_after_login IS,
* it will log the user in normally, to whatever login page they've specified in their account.
