This reverts most of commit a50a2111, where the
-Werror,-Wunused-variable for SwView::SetMoveType's aColor (after
3e8fe4d8 "Remove the Navigator buttons below the
scrollbar in Writer" had removed its use) had erroneously make me think that
SwView::SetMoveType now effectively didn't do anything anymore, failing to note
the

  m_nMoveType = nSet;

part that was still relevant.
