Modified CreateAnonymousContent() so that if the text widget has
a default value, it adds it as a text node under the div after it
is created. Add better error checking to avoid possible problems.
Removed calls to SetTextControlState() that were used
to initialize the text widget contents from GetPrefSize() because
it was causing a reflow within a reflow and the editor to be re-entered.
Added missing call to GetText() in Reset().
