Add Facebook icon and email icon next to each individual that takes you ...

...to their facebook profile, opens up an email to them.
Its just more efficient. Its nit-picky, but instead of calculating `_.flatten(_.pluck(people, 'email_address_ids')` for every email address, it would only have to do that once. What if someone was dumb enough to add 50 email addresses, it would rebuild that array 50 times, when it could be done once. Does that make sense?
