Qualtrics Survey Xblock

  Author fields in Studio:
   - Display Name
   - Survey ID
   - Your University
   - Link Text
   - Parameter Name for UserID

  If Parameter Name is left blank, the anonymous student id is
  omitted from the url.

  Links to an already existing Qualtrics survey.
Can we refactor this to not depend on this ID? This identifier seems
"common" enough that I'm worried about it conflicting with existing
items on page (if not now, then in the future).

And yes, I did use IDs for the input fields in the template above. Even
though the identifiers are pretty well namespaced, I'll still be looking
to refactor that in v2 :)
