Implement focus handling for containers

Browse source 
The previous implementation of focus handling assumed that only views can be
focused. Containers can also be focused with a command like `focus parent` or
`focus child`.

Change `set_focused_container()` to handle the case of the given container
being a container with children and update borders accordingly.
