Tibor Nagy 2eb9620415 LibGUI: Improve TreeView keyboard navigation ...

This commit adds two new behaviour to the key event handler of
the TreeView widget:

Pressing left now jumps to the parent node if the current treenode
is closed or has no children.

Pressing right now jumps to the first children node if the current
treenode is open.
