Incorrect Method Signature for dijit.Tree.onClick

[ptwobrussell]

The method signature is not correct, as it omits a second parameter that is passed in from _onClick, which is a reference to the node that was clicked. Without knowing about that second parameter (which you would not unless you read the source to _onClick), you have to resort to "unapproved" methods of getting a domNode reference when a tree node is clicked. See the patch below for clarification:

                // summary: user overridable function for executing a tree item
        },

This may not seem like much, but it's an important omission in the API to fix, because without it, makes a very common operation impossible to perform without munging private members (which even to figure that out takes some time).
