Redesign cosmetics

CosmeticsMenu replaces the cloak and hat menus and stores: the player on
the left, turned by dragging, and on the right Cloaks and Hats tabs over a
grid of every cosmetic. Clicking an owned one equips it, and clicking one
not owned yet claims it, which is free. The equipped one is outlined and
badged, and the grid asks to connect when there's no Saturn session.

SkinPreview is now a drag-to-rotate player view, and its EntityDrawer draws
the player filling a box at a given yaw, returning false when there's no
player. CosmeticPreview and TabMenu go with the old screens.
