Add minor changes and seed / leech in the search view.

Hello !

Thanks for your work. I decided to help you enhance it if i can (I am still an amateur in python).

First i added the utf8 code at the beginning of the 3 python files. Then i changed the code a bit to make it more PEP8-like !

Then i changed some data into search.py to be able to show seeds and leeches for each torrent in the autosuggestion.

Hope you like it !
