initial branch commit

First try of a rtorrent module based on Chris Lucas' rtorrent-python api and the utorrent module code. 

Source doesn't look pretty and the template definately needs some more love but basic features are supported:

- connect to rtorrent (scgi url tested)
- list all torrents with the following information
  - torrent name
  - download progress bar, percentage, time remaining
  - status (seeding/busy/done/inactive)
  - seed ratio
