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.
