Kamyar

1. Added shebang so that after "chmod +x setup.py", installation can be achieved by "./setup.py install"
2. base_url is now being used to derive search_url & latest_url
3. base_url is now being read from conf.cfg file for easy modification(some countries censor kickass.to) , user may now change it without inspecting kat.py)
4. sorting option is added to popular(), it is now supported to do sort it by kat.popular(sortOption = <option>) where <option> is an attribute in Torrent class(currently there is the 1 GB < 2 MB, 1 day < 12 hours bug, gonna be fixed soon)
