add cf2 route to apache conf

Adding a /cf2 route to the apache conf template.  I'm using this route to serve up the Arturo UI on the Tropo server for testing.  You'll need to add it to you apache.conf if you want the beta on/off toggle to work.

We can remove this once we have a *is_beta_user* flag in the profile object and the Tropo server is capable of fetching the profile to determine which experience they should serve up to the user.
