Fixed
- Zia Settings shows how each setting is actually set. Every switch showed off:
the settings were handed to the page in a way that didn't reach it inside Zen.
Changes made on the page reach Zia two ways now too, as the welcome tour's do. - Zia Settings keeps up with a setting changed while it's open (in Sine's list,
another window, or one that turns itself back off, as "Show the welcome tour
again" does): it showed what it had first. - Zia Settings opens again if asked to just as it's closing; nothing opened.
