3.1 SearchWidget graphic fix

KennyHoran

Here's another fix for the SearchWidget. When the search layer is changed on the text search tab, the search label flashes to the left. Switching the RichEditableText to a lightweight Label removes the flash.

<s:Label id="txtLabelText"
  width="100%"
  editable="false"
  text=""
  textAlign="center"/>

I can see the jump/flash (which warrants a fix), but we want to keep it as RichEditableText so that it is possibly to copy the text (like the example text string).
