Looks like the ability to view other users apps as a cloud foundry
administrator had not been implemented, although a link from the users
page implied it had.

Adding in functionality so that an admin user can switch users.
Sadly the way this is written in most causes exceptions going up the
stack cause the controllers to set a flash[:alert]. However the haml
pages still try to parse arrays that are all nil causing multiple errors
(and no flash alert). We see occasional bad stats calls on our cloud,
which can break the entire page. Ignoring exceptions for stats at a
lower level to display as much as we can get.
