re-initialize ember app

this is a really messy commit!  Basically it was necessary to
re-initialize the ember application.  Then I did some work on top of it.
changes title
Add D3
make connection to know dougall backend ssl

not really important for this story, but doing it hear anyway.
renames ember app env var in back end
adds route with models to friends graph

* connected users are sideloaded
adds the login button to fetch the user info
adds friends graph component

I thought I already added the route?
adds chosen connection sidebar
keep logo on top
adds show route

this will be hit when someone else logs in
adds tests for all of this

These are so far being ignored.  Want to get it all up and running
before investing in tests
keep side nav on top
Merge branch 'add-friends-graph'
