Add facebook profile link

[palchrb]

Would be excellent if search returned the link to the facebook profil as well. E.g. that either the ID or the name was a clickable link to their profile. Should be easy to implement as this link can be used to access the profile of a given ID number: https://www.facebook.com/profile.php?id=XXXXXXX

Too quick - not that easy, as it only works for the shorter IDs, not the longer meta IDs. So would probably need to get the vanity ID or something like that from the api to build working links for all ID number types.
