Requires a corresponding change to external/webkit. We were previously letting WebTextView handle clicks, determine the change in selection, and pass that down to webkit. This sometimes resulted in a different placement of the caret if the WebTextView and the webkit-rendered textfield did not line up exactly. Now, we pass the click directly to webkit, which determines the new selection and passes that info back to the WebTextView. This also has the benefit of letting the WebTextView reflect changes in the selection that originated from webkit. Also remove some unused parameters.
