- Navigating between COMBOs using the ComboBox works. I tested it a little and
  it works. :)
- Changed the functions of Cell Locator to accept a bool setFocus of the grid.
  useful when populating grid with buttons without disrupting other controls.
- The code of OnChangeComboName event is copied from SaveToGrid function.
  It needs to be merged.
- various cleanups :)
