Fix route in URL after refresh

#83
Moved the backbone.history.start to run after the login has succeeded.
That appears to have fixed things.  From the docs you are supposed to
have all the modules started and then run the history.start.  I think
we had them out of sequence after adding the login validation and
context creation.
Change logout to hard link

#76
Change logout from backbone route to hard link to logout.html.
logout.html kills the cookie (sets value to 'missing') and then
redirects to the base url which restarts the whole app from scratch.
