Ported to python 2.x

[sirchia]

Hello Pavel,

I'm planning to use your utorrent library in an existing python 2.x project and therefore had to port it to make it compatible. As I am very new to the python programming language so you can imagine the porting was quite a daunting challenge, but I think I got it all working.

I'm sharing my modifications with you, hoping that you might review and/or improve them and perhaps you want to host them in a different branch/repository yourself as a 2.x alternative to your 3.x library.

Please let me know what you think, I'm always eager to learn.

Kind regards, Riccardo
