Title: add handling for the left key

Change the left cursor key handling in the files view. Specifically, a left arrow on a container that is expanded will collapse that container. A left arrow on anything else will select the parent of that element.

@dinhviethoa for review. Hoa, I have one question in the CL - given a uuid for a child node in the files view, how to I get the uuid for its parent?
