That is why the header_type('none') is a bit of a hack. You have to
handle stuff that CGI::App is suposed to handle for you. When you set
header_type('none'), you have to send out the headers yourself, and
then you can call 'print' in your runmode to your hearts content, and
at the end you can just return ''.
