Adds Per Provider Seed Ratio (needs further testing)

Adds Per Provider seed ratio for all current torrent providers apart from custom providers (rss feeds) users have added (I will add this at a later date).

Support for these clients has been included:
    utorrent (tested)
    transmission (untested)
    Deluge (untested)

rtorrent seed ratio support is currently disabled in SickBeard so I haven't been able this yet.

I haven't got a working linux box setup at the moment so I haven't been able to test to make sure transmission and deluge are working correctly - so I've marked this commit as needs further testing. 

Additional note: the seed ratio boxes I have added don't quite line up with the username and password boxes on providers that include these. If anyone good at web design can have a look at this I will be very grateful ;)
