[bug 926921] Show everything to folks with permission

This adjusts the response details page to show all the details (except
the email address) to people with "clearance".

At some point, we should talk about what's ok to show everyone. It's
possible all this information is fine to show everyone.
[bug 935632] Add intermediary account creation

This creates a UserProfile model which doesn't do a whole lot yet other
than let us denote new users.

This updates all the places where the user's name shows up to use
get_display_name().

This adds a FjordVerify class which sends new users to the creation
page. Right now this is sort of a stub and allows us to create a
UserProfile. At some point p, this will be important and will have a
profile creation form and also tell the new user what he/she can do on
Input.
Nix trailing whitespace
Redid Profiles, redid permission checking
