Broken HTML when user not logged in

[solarissmoke]

Hi,

I spotted a couple of issues on uchaguzi.co.ke:

1. The doctype is for XHTML 1.0 Transitional, but the code uses HTML5 elements (header/footer etc) which causes issues in some browsers. I think changing it to the HTML5 doctype will fix that.
2. There's something not quite right in https://github.com/ushahidi/uchaguzi/blob/master/application/views/header_nav.php . The .userinfo div is opened at the top, but is only closed inside the if($loggedin_user != FALSE) block. Similarly, the .userdata and .userinfodrop divs are only opened if a user is logged in, but are closed regardless. This results in unbalanced opening/closing tags for anonymous users which breaks HTML further down the page.

I would submit a pull request but I'm not sure what the intended structure of these divs is for logged-in/anonymous users!

Cheers,

Samir
