Add support for FF and browsers that will not redirect from HTTPS to HTTP

Add support for browsers that for whatever reason
cannot redirect to localhost (Firefox being one,
since it will not redirect from HTTPS to HTTP
with JavaScript).
Now if a request comes in that does not originate
from a AJAX call a 303 reply is sent which will
redirect the user to the correct landing page.

This requires a change to the force-cli webserver,
I have that change for you, just let me know how 
you'd like to review it.
