µTorrent 1.9 alpha 13485

New alpha! The main change is that uTP (UDP torrenting) is added and enabled by default. It also has real-time transfer rate control and latency minimization.
This build will probably download slower than 1.8.1, particularly if the entire swarm is 1.8.1.

If you are experiencing slow upload or download performance please try 13520, which should generate "socket.log" and "utp.log". You don't need to run it for more than a minute or so once the transfer rates stabalize.
