SpendThrift 3: Dynamic Categories

It's easy to forget about it, since SpendThrift has had this feature since day one, but dynamic categories are nice. No editing any silly list, trying to predict how you're going to organize things. Organization is a thoroughly mutable process, and you really never know until you've been doing it for a while what the best way to classify things is. So create categories to your heart's content. SpendThrift will keep track of them for you.
