Smarter focus handling

[GoogleCodeExporter]

Focus shoud be somewhat smarter.
The user should always be able to use the keys (provided, that the tree
itself has the focus), so there should always be exactly on focused node.
The focus must always be on a _visible_ node.

  * on init focus root (or first visible child, if root is hidden)
  * whe the tree container is clicked, or gets focus, make sure that
exactly one node is focused
  * when a node is collapsed, and a child was focused: focus the node
  (see also issue #10)
  * when a folder is clicked to expand: focus it
  * whwn a lazy node was

  * when [tab] is used to move inside the tree container, then the
ui-dynatree-focused node should get the focus
