Subject: [PATCH 1/3] searchbar: Add a key-capture-widget property

This is handy to set up this relationship in ui files,
and also makes it accessible in the inspector.

Subject: [PATCH 2/3] gtk-demo: Make the search bar appear for typing

Having the search bar present from the start is
a bit jarring. Make it appear when called for.

Subject: [PATCH 3/3] demo: Clear filter when search is stopped

reset the search string to "", so we don't
end up with a filtered list and no obvious
way to remove the filtering.
