Allow personalized Default Filters for Litter and Breeders screens

Currently my litters list view defaults to youngest litters first. I rarely ever need to see younger litters first, it's always older litters that I'm most actively editing. It's a pain to reset the order every time I go back to my main litter page in between editing litters, especially when I have a lot of litters and it takes time to load. It would be nice to either switch the default back to oldest litters displayed first, OR allow individual users to set their own display defaults so they don't have to keep changing them every few minutes as they click back and forth between screens.

Thanks!
