Extra closing div, extension for registration page

Hello!

Thank you for this really cool plugin. I was glad to finally find a good captcha implementation for wordpress.

Seems like you have an extra </div> in plugin code on line 149 of securimage-wp.php – I tested plugin on several themes, and this div was always extra.

Also, I wanted to use your plugin for registration page, and made extension for it – http://wordpress.org/plugins/securimage-wp-reg/ – once activated, it adds captcha for register page. Also it fixes this </div> problem : )
If you fix it in future versions, please define constant SIWP_DIV_FIXED – and my extension won’t replace your function any more : )
