Add a way to search the Tome Archives for challenges by keyword

dugman

With soon to be 12 Tomes in the game now with four chapters each it's becoming increasingly hard to look for challenges involving specific characters (e.g. if I want to play as Spirit, and I don't happen to know off-hand which Tomes involved Spirit, you have to kind of flip through everything to look for them.) It would be a really handy feature if there was a search bar on the Archive screen where you could type a keyword and it would give you a dropdown of challenges including that word, maybe putting uncompleted ones at the top.
