Prevent Squirrelmail from showing its version (2)

Another shot at this, the one before used the setting for displaying a custom logo, sort of branding with a link, etc, etc.
This one, uses no logo at all, but the provided blank png file, so it will present a clean login interface, and, more importantly, no disclosure of the Squirrelmail version.

$org_name        = " ";
$org_logo        = SM_PATH . 'images/blank.png';
$org_logo_width  = '1';
$org_logo_height = '1';
$org_title       = " ";
$signout_page    = '';
$frame_top       = '_top';

$provider_uri    = ' ';

$provider_name   = ' ';
