Rafal Luzynski 3c253c46a5 flowbox: correct the behavior with "can-focus"==FALSE
In fact there were two issues:

1. GtkFlowBoxChild with "can-focus"==FALSE should pass the focus
to its child immediately.
2. GtkFlowBox with "can-focus"==FALSE should cease its custom keynav
implementation and fall back to the default GtkContainer behavior
which is more natural.

Thanks to these changes the flow box can act as a better replacement
for GtkGrid and similar containers.
