updated to new nsCOMPtr usage
nsTextEditor::InsertBreak() implemented
  splits the text node at the caret (deletes any extended selection to force a collapsed selection.)
  inserts a <BR> which I assume we'll convert to a CR when we write to a text stream.
  undo and redo work, except for the bug noted below

More stuff:
interface cleanup
strategic debugging code added
delete selection txn sets the collapses the selection...this is just a placeholder, but I needed it for undo/redo of InsertBreak.
join and split now work for text nodes as well as interior nodes
