[cp-patches] Patch: JTable and JTree fixes

[Lillian Angel]

Fixed a NPE in JTable.
Fixed some issues in JTree, where the root or children are set
explicitly to be invisible.

        * javax/swing/JTable.java
        (tableChanged): Cleared selection if there are no more rows. 
        Prevents a NPE.
        * javax/swing/JTree.java
        (scrollRectToVisible): No need to set the selection path here.
        (expandPath): Sometimes it is required to set the state of a 
        leaf, especially if the leaf is the root node.
        * javax/swing/plaf/basic/BasicTreeUI.java
        (getRowCount): Added call to updateCurrentVisiblePath, so the
        correct value is always returned.
        (paint): No need to paint if the visible path is null.
        (propertyChange): Implemented.
        (paintRecursive): Added check for visibility of child. If it is
        not visible because it was explicitly set to be hidden, no lines
        should be drawn.
        (paintControlIcons): Likewise.
        (getPreviousNode): Fixed check to include root.
        (paintRow): Set focus to be true (this will change in the 
        future).
        (updateCurrentVisiblePath): Fixed check to call getNextNode if
        the current node is a leaf (more efficent than calling 
        getNextSibling).
        * javax/swing/tree/DefaultTreeCellRenderer.java
        (getTreeCellRendererComponent): Changed to draw border if node 
        has focus.
