this changes the login/logout/cookie behaviour
if you go to /quarantine
you get to the loginview
except you have a valid cookie
or you have a ticket via url (this takes precedence)
when you have a valid login
you go to the quarantineview
else if you have not a quarantine ticket
you get to the mainview
else
you get to the loginview
also adds a logout button to the quarantineview
and moves the viewchange/logout logic to the Application.js
