the dressing room opens, and the pet gets its paper doll

- ctrl-click an item to try it on: the dressing room dresses your double, and shift-click posts the item link to chat
- the pet tab lands in the character window: paper doll stats, family and diet, the right-click menu, and dropping food on the pet feeds it
- water-only spells refuse on dry land: aquatic form gates to swimming, client-side like the real one
- the macro icon picker's white squares get their art back, and option rows explain themselves on hover
