Make tree to tree diffs case sensitive

Browse Source 
When case insensitive tree iterators were added, we started reading
the case sensitivity of the index to decide if the tree should be
case sensitive.  This is good for index-to-tree comparisons, but
for tree-to-tree comparisons, we should really default to doing a
case sensitive comparison unless the user really wants otherwise.
