file-browser: expand/collapse item on right/left keypress

Browse Source 
When an item is selected in the file browser:
 - when the left key is pressed:
   - if it can be collapsed, collapse it;
   - if its parent exists, go to the parent;
   - otherwise, do nothing;
 - when the right key is pressed:
   - if it can be expanded, expand it;
   - otherwise, do nothing.

This mirrors the behaviour of Nautilus
(before the tree view has been temporarily removed).
