Fixed some keynav problems:

    No focus, hitting down would skip first item
    Enter key to toggle was falling through to other widgets
    Removing an item that has focus clears item focus (to prevent wild ptr)

Added new methods:
	Fl_Tree::get_item_focus()
	Fl_Tree::first_visible()
	Fl_Tree::last_visible()
	Fl_Tree::is_vscroll_visible()

Simplified + fixed Fl_Tree_Item::next_displayed()

Fixed Fl_Tree_Item::visible_r(), was skipping item if it was a closed branch.
