list box: Make focusable headers possible

Desktop / GNOME / GTK - Matthias Clasen [redhat.com] - 21 August 2015 19:51 UTC

Previously we were assuming that only list box rows could occur as focus children of a list box, and would crash if that wasn't the case. This commit handles this case, and integrates focusable headers into directional keynav and the focus chain.

The typical case of using separators as headers is not affected by this change.
