Subject: [PATCH] Implement doCommandBySelector for the wxNSComboBox class

* Use the same code as for wxNSTextField (copy-pasted).
* This method is used to redirect the enter key event to the OnChar
  event.
* This makes it possible to implement the default button activation by
  pressing the enter key (for comboboxes which doesn't have the
  wxTE_PROCESS_ENTER style).
