The shapes and comments code in sw and sc assumes
that OutlinerView::Paste does paste as unformatted
text, and OutlinerView::PasteSpecial does paste as
formatted, similar to the corresponding methods of
EditView, which it's supposed to call internally.
But the reality is that OutlinerView::Paste just
calls PasteSpecial, with a comment "HACK(SD does
not call PasteSpecial)". All this situation goes
back to "initial import" commits.

This commit changes OutlinerView::Paste to paste
as unformatted (by default). Call sites that were
using it, but apparently wanted formatted output,
were changed to an explicit PasteSpecial call.
