My first go at a KDE patch.
Exports if a peer is connected with a uTP socket from libktorrent using PeerInterface, similar to how the encryption state of a connection is exposed.
Adds a column to peers tab of the Info Widget plug-in which indicates if the connection is uTP.
Patches are against Trunk as of 10PM PST June 19th 2010 (4.0.1+, 1.0.1+). Briefly tested on Ubuntu 10.4. Might need translation files.

I will check them out

Looks like a cleaner version of my patch made it in. Thanks!
