Adds Per Provider Seed Ratio

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~~) - Edit: Now tested
    Deluge (~~untested~~) - Edit: Now tested

rtorrent seed ratio support is currently disabled in SickBeard so I haven't been able to add 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~~ Edit:now fixed
