plumb the data for top PACs to the "View all Oregon" page

All the pieces were there, just needed to be hooked up.
One small comment: I resolved the 3 donor lists together in a $q.all
because simply setting the fields in the donor object didn't seem to
trigger the $watch on it. Creating a new object with all new fields
did the trick.
bug fix: update the nav bar when viewing oregon

when I changed the route from 'view_all' to 'oregon' I neglected to
update the nav controller to check for it. That's what I get for coming
up with a strategy that relies on checking the route for hard-coded paths.
