Matthias Clasen 8a0035333a a11y: Set focus-related states properly
Entries and menubuttons are no longer focusable themselves,
they have focusable children. Since we don't have accessible
objects for those, transfer the focus-related state (focusable
and focused) from the children to the main accessible object.
