Add Filter to Progress

[LutzRyan]

In my collection, I have multiple lists setup. One use case is that I have a list of shows I watch alone and a list of shows that I watch with another person. It would be great if the progress screen supported a filter to only show items from one of my lists. If I'm with another person and we are deciding what to watch, we can look at the filtered list of only the shows that we watch together to determine what is new and what we want to watch. The filter could also show watchlist, archived, or all items, which might help resolve issue #443.

I think it's a quite interesting idea. I'm leaving this to think about later.

Filtering by genre or network would also be amazing.
