Add Won/Remaining backgrounds and species to clan/user pages

[tasonir]

Just like there is a Won and Remaining section for gods, add a section for won/remaining species and backgrounds (not combos) for clans and user pages. It'd probably be tough for a single player to finish the list, but clans could use list to plan out final remaining races/backgrounds to play to maximize their points. As far as I know you currently have to either query the bots or check it manually, both of which seems tedious.

And maybe someone out there with a streak of 15 might want to know what choices they still have left, and this will give them a convenient list to check
