Show additional Profile Fields / add a Field to show additional Info

[gooloonetwork]

Hey. :) My first Contribution on GitHub, so please don't scream at me. :D

I use a Function like
function custom_user_profile_fields($user){ if(is_object($user)) $skintype = esc_attr( get_the_author_meta( 'skintype', $user->ID ) );

to add some additional Info, like Skin- and Hairtype (Beautyblog). It would be awesome if there was a field where you could add PHP or Shortcodes to show such Information beneath a User's shown Name.
