[cp-patches]: Patch: JTree related class' implementations

[Lillian Angel]

I have been working on JTree quite a bit. Most of it was not
implemented. There is much more I still need to implement, but this is a
good portion of it. Right now, I am working towards selection on the
JTree. As of now, alot of methods have been implemented from several
classes, and the JTree is responding to mouse clicks. By visual testing,
not much looks different from before. From the classes I have modified,
there has been alot of formatting, so the patch may be cumbersome to
look at. Above all, this patch brings JTree (and its related classes)
closer to being implemented according to the API. I will continue to
submit my changes in chunks... alot has been done, but there is alot to
more.

Patch attached. Approval Pending.

        Several variables, instances and methods were adding according 
        to the API. The methods that were added and not in the list 
        above, have not been implemented yet. All JavaDoc is updated, 
        as well as formatting.
        * javax/swing/tree/AbstractLayoutCache.java:
        (getNodeDimensions): slight modifications to return initialized 
        Rectangle when the bounds are null. Implementation not complete.

        (addSelectionPath): Implementation
        (addSelectionPaths): Implementation
        (removeSelectionPath): Implementation
        (removeSelectionPaths): Implementation
        (getSelectionPaths): returned the selection array
        (clearSelection): set the selection array to null
        * javax/swing/tree/FixedHeightLayoutCache.java:
        (setModel): removed this method because it is defined in the 
        abstract parent.
        (setRootVisible): removed this method because it is defined in 
        the abstract parent.
        (setRowHeight): removed this method because it is defined in 
        the abstract parent.
        Also, some formatting was updated.
        * javax/swing/tree/VariableHeightLayoutCache.java:
        (setRowHeight): removed this method because it is defined in 
        the abstract parent.
