weld SpellDialog

a) use EditEngine instead of TextEngine as the former can be hosted in a
foreign widget
b) use a SfxGrabBagItem to hold the custom spellchecking info inside the
EditEngine
c) in longer paragraphs the current word is now auto-scrolled into view
d) rename Invalidate to InvalidateDialog
