In fact, there are some basic a11y codes for gtkhtml. We just want to
make it more accessible. For gtkhtml2, no one knows when the editor will
be added in and no one can be sure evolution will use gtkhtml2 for its
mail.  Anyway, it may happen in the future. 

But now, it seems make the gtkhtml accessible is a more realistic  idea.
