ajaxlogin & updateLogin log the user in w/ AJAX. 

loginlogoutdirectives - after the user logs in or out through AJAX, this function will dynamically change things on the page that depend on the user being logged in or out.

ajaxlogout & updateLogout log the user out with AJAX

getloginbox & showloginbox grab the login box w/ AJAX. getloginbox receives several vars. loginforcereload will force the page to reload after logging in.
