ENH: Remove generation of unused Update.xml parts

This removes generation of some Update.xml content that is not used by
any Dart1, Dart2, or CDash servers:
  - Revisions elements
  - Directory attribute of File elements
  - File elements within Author elements
The content was generated only because the original Dart1 Tcl client
generated it, but the content was never used.
