Fix crash when editing wxDVC items in place in wxOSX/Cocoa.

Browse Source 
NSOutlineView::editedColumn: and editedRow: return -1 when they are called
from textDidEndEditing so we need to store their values in textDidBeginEditing
and reuse them later.

This fixes the crash in the sample with out-of-range array index exception
which happened whenever a cell was edited.
