Update the "Running a Bridge" section of the website

Tom Ritter reported that the information at the bottom of https://www.torproject.org/docs/bridges.html.en#RunningABridge on running a Bridge relay is very out-of-date. We should probably:

1. Move it to a separate page, because it's intended for a different audience than the rest of the page.

2. Explain that operators should be running Tor>=0.2.5 if they want to offer pluggable transports.

3. Update it to explain the minimum requirements for running an obfs4proxy bridge, and give an example torrc like:

ORPort 1.1.1.1:62419 ORAddress [2001::f00]:62420 ExtORPort auto RunAsDaemon 1 ExitPolicy reject :

BridgeRelay 1 ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy ServerTransportListenAddr 1.1.1.1:80 ServerTransportPlugin obfs3 exec /usr/bin/obfs4proxy ServerTransportListenAddr 1.1.1.1:443

ServerTransportListenAddr is entirely optional. A better place to check would be /var/lib/tor/state (TransportProxy obfs4 addr:port), assuming tor has finished guessing it's IP address.

The ServerTransportPlugin line can be unified as well to ServerTransportPlugin obfs3,obfs4 exec /usr/bin/obfs4proxy.
