[Whishlist] Multiple source of RSS for the same filter list

[MageMinds]

It would be useful to have more than only one RSS site link for the same Filter list, so if one site goes down the other one is used, sabnzbd would use them in the order of appearance.

That would allow me to assign two different source for my TVShow both are very similar in the name they uses so the dupe checker would not be fooled into downloading multiple times the same nzb.

That would be a great feature. It's really bothersome  when my Main RSS feed goes offline and I manually grab NZBs,  then they download automatically when the feed comes back online, so I get 2x of the same show.

If we can fit it in without making the UI too complex, it's quite doable.
I'll add it to the todo list.
