Basic redirection routine supporting multiple targets and methods.

Call:
 
ff_redirect($url [, $target='self' , $method='post'])

    $url    = The url to redirect to including the parameters appended.

    $target = 'top', 'parent', 'self' or 'blank'

              'top'    = redirect to the top browser window
              'parent' = redirect to the parent frame
              'self'   = redirect in the same frame (the default)
              'blank'  = redirect to a new browser window 
                         (blank works with post method only)

    $method = 'post' or 'get'. The default is 'post'.

    Example:

       ff_redirect(
          'http://mysite.net/index.php?option=xxx&Itemid=33',
          'top'
       );
