Standardize default server-side FTE ports

[kpdyer]

In the current release the FTE server binds to 127.0.0.1 on port 8080 and we forward all data to port 8081. This is probably not correct for most deployment. As a few examples of changes we want to make, we could make the following assumptions:

(1) FTE will bind to port 80.
(2) There will be a Tor bridge on the local machine running on port 9001, and we will forward all requests to this port.

However, should the FTE server reject a request to port 80 using a non-HTTP format? Or should the server just allow any supported format on any port?
