Send generic wxListCtrl wxEVT_COMMAND_LIST_KEY_DOWN events from OnKeyDown rather than OnChar. Also remove the HasCurrent check. These changes bring the generic control into line with the control under wxMSW. Re-enable the previously failing unit test and document that the key down event might not have a valid item associated with it.
