Subject: Remove CPWL_Edit rich text support

This CL removes the code which attempts to provide rich text support for
CPWL_Edit. The code, as written, doesn't actually work well.

If you have tags under the <p> tag we will just lose the content (so
<p><b>foo</b></p> would end up being a blank string).

Multiple <p> tags get concatenated together with a \n, but we
subsequently lose the \n later when we store the content into the
VariableText object (so <p>foo</p><p>bar</p> becomes foobar instead
of foo\nbar).

We never read the "RV" field from the dictionary. The RV field is what
actually stores the rich text value. So, we never set a rich text
value into the text edit.
