enhance make_clickable so that it allows for anchor attributes to be passed via an extra array argument.

When using make_clickable it is useful to pass in the extra anchor attributes to be included in the function call.

One can call the function like this if you need to include anchor tag attributes

$attributes = array(
    'target' => '_blank',
    'class' => 'external', 
);

make_clickable(  $text  , $attributes  ) ;
