More categories in CAS

Please add more categories for things in CAS - add an underwear category like we had in Sims 2(I think that should have been added with the Simtimates kit, really), give birthmarks their own category(because we need the Skin details one for Skin Overlays), add a category for body piercings, and split facial piercings into three(or more, but i think three would be fine) categories - ear piercings, nose piercings, other piercings.
