Fix failing mailto spec and add full_name method.

Now that the alternate name has been added, it broke the mailto spec
on master since the spec was using the full name (including alternate name),
whereas the app was only using the name.

I changed the mailto method to use the full name in both the subject
and body, and created a `full_name_for(location)` method, and used that
in the results page, details page, and header as opposed to keeping the
logic in the views.
