Warnings in new inset code

[Jean-Marc Lasgouttes]

I get the following warnings when compiling with cxx (I get others
too, but I have corrected them in my tree). Is there a reason why
UpdatableInset::InsertInset() and UpdatableInset::SetFont() do not have
the BufferView* parameter?

cxx: Warning: ../../../lyx-devel/src/insets/insettext.h, line 101: 
          "bool InsetText::InsertInset(BufferView *, Inset *)" does not match
          "UpdatableInset::InsertInset" -- virtual function override intended?
    bool InsertInset(BufferView *, Inset *);
---------^
cxx: Warning: ../../../lyx-devel/src/insets/insettext.h, line 105: 
          "void InsetText::SetFont(BufferView *, const LyXFont &, bool)" does
          not match "UpdatableInset::SetFont" -- virtual function override
          intended?
    void SetFont(BufferView *, LyXFont const &, bool toggleall = false);
---------^
