Fixed
- Zia Settings works: it shows how each setting is set, its switches change
them, and the ✕, Esc and a click outside close it. It was a page of its own
in a frame, and inside Zen nothing passed between it and Zia: every switch
showed off and it couldn't be closed, short of restarting Zen. It's drawn in
the window itself now, as Zia's other panels are.
