DRAKHYSYS INFINITY WORKBENCH V4.8.8.44

UI INTERFACE / NEW GAME FLOW EDITOR

NEW: Hide original BG2 START UI checkbox.

- Checked: the custom interface becomes the real START screen shown when BG2EE opens.
  No Planetar/entry button is required or inserted.
- Unchecked: the original BG2 START interface is restored on export. The optional
  Planetar/custom-menu entry button works as before.
- Restoration is reversible even when the already-exported override/UI.MENU is
  selected as the next base file: the exact original START block is preserved in
  a managed backup comment.
- Existing independent SoA / ToB / Black Pits II visibility toggles are preserved.
  While the original UI is hidden, add stock campaign actions as buttons on the
  custom interface if desired.
