Fixed
- The copy link button (the paperclip shown when you hover over the address
bar) could go missing for good: Zia puts it beside Zen's site settings
button and gave up if Zen hadn't added that button yet when Zia started,
as could happen just after installing Zia. Zia now waits for it, and if
the paperclip still isn't there, Zen's own copy button stays instead of
being hidden. Thanks to $loth
