Update obsolete comments in domado.js and narrow domitaModules scope.

* domitaModules has no reason to be a global variable, so move it inside
  the scope function.
* Update copyright date.
* Node lists are no longer not live.
* Domado may not be a “full implementation”, but it's not like we are
  specifically planning to replace it with something better.

Note: The simple move of the declaration of domitaModules into the function was
rejected by our linter, so I instead merged it with the conditional
initialization domitaModules = {} later down in the file.
