message: Add config settings to renderdocui to avoid extremely dubious redirect
  * IronPython >= 2.7.5, if installed, adds a *global* redirect so all
  programs (like renderdoc) that tried to reference the 2.7.4 they
  provided will instead get redirected to 2.7.5. Whether or not it even
  exists.
