Implemented a new CAPTCHA API; the frontend ($session->{make,get}_captcha) is API-compatible but the backend (the captcha class) is deprecated.
input.radio {border:1px none #000; background:transparent; vertical-align:middle;}
.panel_wrapper div.current {height:80px;}
#width {width:50px; vertical-align:middle;}
#width2 {width:50px; vertical-align:middle;}
#size {width:100px;}
