Add convenient wxListCtrl::AppendColumn() wrapper.

In the vast majority of cases, columns are just appended to the end and not
inserted at arbitrary positions in wxListCtrl so provide a convenient wrapper
to do this, especially as it's really trivial to do it now when it can be done
only once at wxListCtrlBase level.
