Fixes Issue #534.
Changes the keyboard navigation on the tree to be more efficient and
more intuitive. The left arrow now expands the current node and
selects the first child if there is one. The right arrow now selects
the parent and collapses the current node and all its siblings. Also
includes many whitespace fixes.
